Could I request Yosafire and Froze as yandere for the reader? Whether competing for S/O's affection or polyamorous is up to you.
Yosafire
Yosafire is your very outspoken stalker.
She watches you all the time with an eager expression and would do anything to spend time with you.
Studying? Let's do that super famous library date! (There won't be any studying on her part though). Hungry? Let's go pick some apples and have Dialo bake apple pies! Have any free time? Let's go to the garden and pick some flowers!
"I'll make you a flower crown, [Y/n]!"
Her diary is filled with countless pages about you, full of praises and her declarations of love.
She's very clingy and touchy. Especially when the two of you are in a relationship. If you let her, she'll hug you and shower you with kisses. Yosafire's shameless when showing affection.
When the both of you are alone, her hands tend to...wander.
If you reject her affections, she'll be disheartened, but not for long. In fact her efforts will double to an almost worrying degree.
"I'm sure [Y/n] will love me one day! I just have to keep trying!"
Basically, Yosafire is just overwhelming.
Froze
Froze is the exact opposite of Yosafire. She's very subtle when conveying her affections.
She'll start by befriending you first. Froze is a quiet one and doesn't really interact much with others that aren't her circle of friends. It would be strange if she just suddenly confessed to you.
Small talks during breaks, asking to go home with you, offers to study together...eventually, Froze becomes one of your good friends.
Once she sees you're comfortable with her, she starts giving hints of her feelings.
If you're particularly dense, then she'll confess to you, blushing and stuttering. It's a stark contrast from her usual calm expression.
Once you accept, then you'll find yourself with a literal guardian angel. Froze always thinks of you and makes sure you're taken care of (and not thinking of doing anything stupid or reckless. She's had enough of that with Yosafire).
She can also be quite manipulative. If she doesn't want you to do something, or spend time with anyone else, then she can immediately get rid of the idea out of your head.
Spending time with her friends are fine, but she'll get very jealous if it's someone else.
If Yosafire is the type to drag you everywhere on dates, then Froze is the exact opposite. She prefers stay-at-home dates where the two of you can cook together, watch movies, and cuddle with each other on the bed. She loves her alone time with you.
If you reject her, then she'll be your guardian angel in a different sense. She'll constantly watch you from afar and make sure you don't fall for anyone else.
