Shota Yasojiro

This redhead will put off anything and everything else that requires his attention. Though he'll call in doctors to tend to her at home, he'll read up on whatever she has to see what he can do for her. Whether that's making a special food or getting medicine, he'll do it himself, without the help of others. For the most part, he won't trust himself to try to take care of her, thinking him in the way or being too smothering so he'll just pace around the room worriedly or read a book to her. If she asks for him though, he won't deny her but will treat her delicately.

Takuya Miyahara

At first, Takuya might panic, but it would eventually turn into little weeps. Of course, he knows what to do, but is scared he may do it incorrectly or make the (h/c) haired girl feel even worse. Once he works up the courage, he would be able to cater to her every need. The main thing he would focus on would be her comfort, but he would also make sure to offer his affection. Should she feel lonely or in the need of snuggling, he'd be happy to oblige. He wouldn't care if he got sick from it. In fact, he'd prefer it, the thought of (Y/n) taking care of him extremely tempting.

Haru Akahito

Well, (Y/n) probably won't end up dead...hopefully. Still, that won't stop the brunette from panicking over the slightest cough or cut, thinking a painful death was in store for her. He'll take her to the hospital, probably one his father owns, and make sure there are multiple nurses and doctors tending to her every need. He'll insist on staying with her, showering her with gifts, and providing things to entertain or comfort her. Sooner or later, he'll pass out next to her bed out of worry, holding onto her hand and refusing to let go until she's better.

Rei Hirasi/Hoshino

Surprisingly, Rei will be quite calm about the situation. Though he's never had to care for anyone else but himself, being the youngest of three brothers, having been given the care instead, he'll do what he can. He won't overreact, keeping a level head and will have her rest at home, making foods that are either a comfort to her or can do her some good. It'll be a rough learning curve for him at first, but he gets the hang of it quickly and is able to provide whatever (Y/n) needs, especially if it involves him singing her to sleep.

Yamato Hisaki

This brunette has a hard time understanding how to take care of others without offering them protection. He cannot physically fight an illness so he'd resort to trying to force it out of her system with the utmost of care. Making tea would be something he would be more than willing to do, especially if it helped ease her body and mind. Though he'd be too jittery about having (Y/n) rely on him and him alone, he'd be determined to do his best even if he can't do everything as perfectly as he thinks she does.

Akari Otsu

Though he's seen (Y/n) sick many times over the years he's known her, it's never stopped the blonde from worrying himself sick. He'd panic and mumble to himself about what he should do for her only to run around the house, looking for things to help her. Eventually, she'd wind up with numerous pillows, stuffed animals, and blankets next to her, Akari smiling nervously. He's not the best at treating other people since he's never taking care of himself, but he's willing to learn and listen to what she requests of him.

Narahashi Shiko

There was a reason little 'Hashi always wanted to be a doctor, and it is certainly from the kindness of his heart. Not only did it grant the money it would take to spoil (Y/n), it could ensure he could care for (Y/n) if the time came. Over their childhoods, he's been the one to care for her, rushing to cater to her every need. He loves the feeling of helping her when she's in need, especially if she thanks him with that smile of hers. A lot of the time, he'll overwork himself trying to make everything perfect for her. If she has a fever, he'll sleep on the floor, letting her have the bed to herself. It's just simple logic to him. If it can make (Y/n) feel better, he'll do it.

Sora Gensai

What? You expect the prideful and cocky son of a yakuza boss to tend to a girl? Well, he would, more than one would expect, actually. For the most part, he's not as qualified as a doctor as he'd like to believe, but he wouldn't let someone else touch or look at (Y/n). She's his, and he'll take care of her himself, damn it. He'll have her lay in his bed, laying by her side as he holds her close. If she wants something, he'll get up and grab it, if she wants to go somewhere, he'll carry her, if she wants to take a bath, he'll bathe her himself. Well, she probably wouldn't let him, so he'll wait impatiently on the other side of the bathroom door, listening to hear if she needed help or was in any danger. But when push comes to shove, if she takes a turn for the worse, he'll put aside his pride and let doctors take a look at her, but he'll hover over them to make sure they're not doing anything "unprofessional".

Asuka Chinen

This orange-haired mercenary is really the only one qualified to take care of (Y/n) on her period, having been through the pain and uncomfortable feeling herself. However, the same could be said for her ability to take care of the younger girl. When she was younger, Asuka used to dote and care for her baby sister all the time, and she would apply what she had learned from it to (Y/n). She's in good hands. What's on Asuka's list to give to the younger girl? Video games, plenty of comfort food, and her constant, loving company that's just happy to be able to do something for her.

Kazuki Hirasi/Hoshino

Kazuki is the elder brother of two. As such, though he was raised in an environment where he could have had maids or other servants tend to his little brothers, he wouldn't have it. He would insist on taking care of them himself, and it would be the same for (Y/n). He'd be jittery while taking care of her, worried she may slip from him but would keep his calm for the most part. There wouldn't be a moment he wouldn't be by her side, keeping her company, even watching over her while she slept. He would fall asleep of exhaustion, but his smile would remain as he laid next to the (h/c) haired girl.

Ichiro Hirasi/Hoshino

Though he wasn't the one taking care of Rei, that responsibility being taken by Kazuki, Ichiro still has knowledge of how to tend to other people when they're not feeling well. He would give (Y/n) plenty of cute animals to sleep with and keep her company while he attempts to make her a meal. It will only blowback in his face, the same happening when he asks Kazuki for help, so he'll resort to having a chef prepare her food instead. He'll also make sure that the (h/c) haired girl is not dehydrated, offering her any kinds of drinks she wants even if it's seltzer water.

???

Caring for people is not his specialty, especially considering the way he grew up. Sparing the details, not only was he used to caring for himself, he was the one that would comfort (Y/n) even if she didn't know it. Though he wouldn't care if others got themselves killed, even a small bruise on the (h/c) haired girl would send him into a panic and rage. Firstly, he would become largely overprotective, placing her in his room and not letting her leave until he was sure she would be alright. In the meantime, he would avoid taking her to a doctor and tend to her himself with homemade medicine and calming techniques.
