Fuyumi Todoroki, the grateful older sister. (Patreon)

Because older sisters are great, and they know how to reward the guy that helped his little brother out of the destructive path he was walking.

That guy is the protagonist of this nice harem manga called My Hero Academia. Nice stuff. You guys should check it some time. Deku is a bit oblivious but yeah that's what you expect from this kind of mango.

Enjoy!
