• imagine Arisa's gay feelings or something catching up to her one day (Kasumi smiling being the final nail in the coffin) and she's like super conflicted and confused about these feelings and Saaya picks up on said gay feelings and basically gives Arisa advice on how to tell Kasumi but Arisa just denies her help but she's actually lowkey grateful for the advice

• So she just drags Kasumi off to the rooftop after school one day so that they won't be interrupted and Arisa just freezes up right before she confesses and Kasumi's just so confused before she makes her assumption and thinks that Arisa found out that *she* likes her and basically tells Arisa that it's okay if they stay friends and shit while having this pure bright smile on her face
• Arisa gets fed up with bottling up her feelings and stuff and just blurts out "FUCK THIS I CAN'T DO IT ANYMORE KASUMI I LOVE YOU" and it fucking shocks Kasumi and it brings her to tears because she's so happy and she thought she was gonna be alone for a looong time
• So Arisa's comforting her, saying that it'll be alright and basically just trying to calm her down
• The rest of the PoPiPas catch up to them but stop at the doorway when they notice a sobbing Kasumi resting on Arisa’s shoulders
Saaya tells them that it’s best to leave them alone for a bit but not before locking eyes with Arisa, shooting a smile towards her.
After the final bell rings, Arisa tells the rest of the PoPiPas that she and Kasumi are heading home together by train. None of them really mind since they all happened to be busy that day.

• Alone in the train, a meek Kasumi finally speaks up to Arisa, asking if she really meant it. Arisa reassures her that everything she said at the rooftop was serious, and that she won’t leave her. Kasumi also asks about their first meeting together and how much they’ve changed and how far they’ve come. Arisa takes this opportunity to thank Kasumi and to spill her feelings even more, but finds that she already fell asleep. Arisa would start berating Kasumi, but she simply smiles and falls asleep beside her.
