Comments of Hoshino, Me O Tsubutte.

I think this story is great it toggles some hard topics instead of acting like life is a cakewalk

Kobayakawa is an unsocial student who lives an extraordinarily ordinary life. One day, he meets a pretty and popular girl named Hoshino who has a secret that nobody knows except her sister and her. That is, until he stumbles upon it too by chance. Her sister had been putting make-up on her every day. Now it's his turn to keep this secret and help maintain her social life!

Hoshino without makeup is so adorable <3
Kinda understand why sensei cant leave her for so long

On Hold: Chapter 3. Story about putting make up for a girl

There's a similar manga name Hime doll but instead makeup it a hairdresser

Starts helping do makeup and keep the secret. He seems to take the job more seriously than expected and seems to hope their connection doesn't end.
