Blackpink Reaction: their s/o is sick and they take care of them
Jennie would be really worried about you. She probably knew you were sick before you wanted to admit it, which made her worry even more. Once you told her, she took that as a sign to go all out and have you in bed all day, letting her cook for you and bring you everything you need. If you told her how much you appreciated it, she’d just do a cute pose and brush it off as ‘I know, I know’, but she’d be really happy you let her take care of you.
Unless you were feeling really bad, Lisa would probably tease you a bit for getting sick. She would take care of you nonetheless, not letting you do anything at all. She would have you sit down on the couch, bundled up in blankets while she made sure you had everything you needed. If you told her how much you loved her for this, she’d smile widely and blush a bit, telling you it was no big deal.
Jisoo’s number one task would be to make you feel good again. That meant not just taking care of you, but cranking the normal amount of jokes and puns up to maximum. She’d try to make you laugh no matter how bad you felt, but would probably just end up laughing at her own jokes (which would make you laugh in the end). She’d get you everything you asked for and check up on you a lot to make sure you were okay.
Rosé wouldn’t know exactly what to do when you were sick. She’d ask you what you would like whenever she could, food wise, temperature wise, mood wise. After cooking for you she’d probably lay next to you, this time not listening to you if you’d tell her to go away because you didn’t want her to get sick too. All she’d want was for you to be comfortable and healthy again.
