Hello! I've been trying to find a story that's a part of set in a Manga. Issue is- the story isn't the main one,so it doesn't feature on the cover or title so I can't just go through my lists (where I probably added the story) (I also checked my reading history,and it's not there as it's been a while since I read the story).


Characteristic:
-A story in a set
-High school setting
-Childhood friends
-One shy/ awkward /quiet bottom
-One "prince" top that actually has a nasty personality.
-Bottom has much darker hair, is shorter
-Top has much lighter hair ,is taller


Details I remember:
-Top and bottom are in the same class
-Top secretly has a bad personality and it is nice to everyone but the bottom
-Bottom desperately wants to stop being friends at first
-Top actually had to work super hard to get into the same high school as the bottom just when the bottom thought he could "finally get away"
-There's a few brief scenes of them as children
-A few of those scenes had things like: Hey! Do my homework for me! And the like
-Top confessed to the bottom first


Top reminded me of a cat tbh.

Any help would be appreciated! Thanks!
