Supervillain Idol System: My Sidekick Is A Yandere

After Summer conceded defeat, Don got off her and returned to his seat. She quickly stood up and approached him from behind, throwing a punch at his shoulder. She put a lot into it, but even then, it didn't have much of an effect, especially on someone with higher-than-normal durability.

Still, Don quickly reacted as if he was in pain. He groaned out, immediately causing everyone's expressions, including Summer's, to change to one of worry.

"Hey, I didn't hit you that hard," Summer said, her voice hinted with a bit of concern.

Don ignored her words and continued to pretend, causing the ever-worried Samantha to immediately stand up from her seat and rush toward him. "Oh no, Donnie, are you okay?" she asked worriedly as she came to his side to examine his shoulder.

She then quickly explained to Summer, "You hit the hand that he had broken, Summer, but he clearly said he's still feeling a bit sore. Oh goodness..." Samantha sighed before breaking away from Don and saying, "Let me go get some pain ointment, okay? And no more roughhousing, both of you," she lectured in a motherly tone before walking away.

Summer wanted to defend herself, but if what Samantha was saying was true, then she did have reason to blame herself for forgetting that Don was still injured. However, she couldn't admit this directly, so she tried to look as unconcerned as possible while avoiding his gaze, though her slightly nervous body language gave her away.

"Don't start fights if you know you're injured, you big dummy," Summer muttered.

Don raised his head slightly and saw that Aunt Amanda wasn't looking. He took the opportunity to glance Summer's way, prompting her to meet his gaze for a moment as he stuck out his tongue in a mocking way.

Summer's expression shifted from surprise to anger as she narrowed her eyes at Don. 'He's faking being hurt by my punch,' she thought before yelling, "Why you—"

Before Summer could say anything more, Don looked away from her and groaned in pain a bit louder, causing Amanda to look his way. She chose to stand up and approached him, asking, "Is it bad?" She stood near Summer to look at his shoulder. "Where does it hurt?"

"My whole hand doesn't really hurt as much, but there's a bit of a strange tingling sensation," Don replied, completely lying through his teeth.

Summer continued to glare at him, no longer buying what he was selling. Amanda, however, fully believed him and was now thinking over Don's answer.

After a moment of thought, she placed her hands on her hips and revealed, "I wouldn't worry too much, then. It should just be your hand reacting to being disturbed as it fully heals up. You see a lot of this in superhuman wrestling. Don't forget, you did just break your hand. At the very least, you need to give your entire body maybe a week to fully heal."

Summer rolled her eyes at Amanda's diagnosis. "Way to put your nude mud wrestling knowledge to use, Aunt Amanda."

Amanda didn't take offense and simply shrugged her shoulders. "You'd be surprised how in-depth the medical commentary can become. I've been applying it to the injuries I got over the years on the farm, and it's helped me considerably."

"Geez, just use a chatbot like every other normal person," Summer retorted.

"Summer has a point," Don added with a groan, causing Aunt Amanda to look his way with a bit of disbelief. "Really? You're siding with her?"

Don tilted his head slightly before adding, "What can I say? She looks like she spends a lot of time in the mud, so we can trust her expertise." Though a terrible joke, since it was at the expense of someone who believed they were being supported, it had an ironic humor to it and caused Amanda to chuckle while shaking her head.

Summer, on the other hand, looked at Don with an even sterner expression before stretching out her hand to try and grab him. "Why you—"

Before her hand could reach him, Amanda stepped in to try and hold her back. "Hey, come on, Summer, you're going to hurt him more."

At this point, since Don was clearly exaggerating his pain and Summer was already being blamed, she figured why not hurt him a little more. So she simply responded by saying, "Yeah, that's the point. He clearly needs a good beating."

By this time, Samantha had come back and found Summer doing this, so she couldn't help but lecture her. "That's enough, young lady. Don't you think you're overreacting? He was only just teasing you."

Summer stopped when Samantha chimed in and immediately wanted to defend herself, but Samantha continued, "And you were just complaining about how sophisticated you are. Is this how a sophisticated young lady should really be acting?"

Summer found herself unable to argue with Samantha's point. More than that, she knew if she tried to say that Don was faking it, they wouldn't believe her. This left her with no option, which very much frustrated her.

"This is unbelievable! Fine, take care of Mr. Injured here, see if I care." After saying this, Summer walked away from the dining table and was about to exit the dining area. But as if remembering something, she came to an immediate halt before turning around and walking back to the table.

She picked up her plate and added a few pieces of chicken from one of the bowls. Only after doing that did she walk away with her plate in hand. As she approached Samantha and was about to walk past her, Samantha heaved a sigh and tried to reason with her.

"Oh, Summer, don't be like this—"

"No, it's fine," Summer angrily replied as she aggressively made her way up the stairs.

Samantha could only heave another sigh as she watched her leave before turning and walking over to Don. "That girl will be the death of me," Samantha muttered as she shook her head.

Amanda just chuckled at this and gave her a little tap on the back. "Oh, don't be too hard on her. She probably just missed roughhousing with her big brother."

"I know, but he's injured. It was bad enough she practically tackled him," Samantha defended, but she wasn't so blinded by her worry for Don that she overlooked his part in the matter as well. She looked at him and added, "And you, Donnie, you know how your sister can be. You shouldn't tease her like that—you're only going to make her act out."

Don nodded in understanding. "All right, I get your point. I'll say sorry to her on my way to bed."

Hearing this, Samantha couldn't help but show a warm smile. "That's better. You two are both too old to be fighting. I'm not getting any younger, so it's going to be you who has to look after your sister should anything ever happen to me."

'Well, I activated the whole motherly lecture, but this is good. It means they're starting to grow used to the way I'm acting and don't find it suspicious at all. I should be fine as long as I don't overdo it and slowly get used to their habits and personalities,' Don thought to himself.
