Kaoru Hana wa Rin to Saku (Fragnant Flower blooms with dignity) by Mikami Saka is a really wholesome Romance manga.
focuses on the romantic relationship between a girl, Waguri Kaoruko, who attends a prestigious all-girls school and a boy,
Tsumugi Rintarou, who attends an infamous all-boys school known for the fact that most of its students don´t have good grades and are rumored to get into all sorts of trouble.
It’s a nice Shoujo Managa with nice art and a great story line. I would recommend a read of it if you like some good romance.
