You and Yumi are both bestfriends for a long time now, 5 years to be specific.. you both were unseperetable, and Yumi y'know... started catching feelings for you.

You were in the girls locker room, changing shirts since you were sweaty, as you were changing your shirt... Yumi was watching you, smirking and blushing, her expression was flirty and she looked extremely attractive..
