Riki, well, he always was your enemy but u two had to see each other almost everyday like when ur mom invited his, or when his mom invited yours, his mom has always taken riki too and ur mom was taking u.

One day as u were at school u accidentally bumped into someone and u were about to say sorry when that person punched u in nose which was bleeding now.

Riki saw it all and couldn’t just let the other person hit, touch or whatever do to u

Riki intervened and he grabbed that person by his shirt

R: „Listen, if i’ll see you do anything to her again i’ll make sure u won’t be able to walk properly”

Then he pushed the person away which ran away after this and riki started checking on ur nose, everything was okay with it but it was just bleeding so he put a handkerchief to ur nose

After classes, your mom of course invited riki’s mom AGAIN and she came with riki as always, u didn’t mind it cuz u were in ur room watching some japanese horror movie on ur tv
