Guess the title

Hey,

I'm looking for a title.

Yaoi manga about a guy who became a hairdresser after highschool. Customer comes in and it turns out that it was his 'bully' from highschool.
Bully doesn't recognize the hairdresser, but does fall in love and hairdresser decides to start dating him to take revenge.

In the end, of course they end up together and the bully didn't really bully the hairdresser, he was just very clumsy when following the hairdresser who took care of plants during high school.
