I want a romance manga where the girl is chasing after the guy and tries really hard, but at some point she gets tired and/or possibly falls apart and does not chase him anymore. Then he gets curious and does the chasing.

Kind of like Nodame Cantabile.

Extra!
Or any manga like Honey and Clover and Strobe Edge.
It's realistic; I can really understand the characters feelings.
I want manga that is mature like these series'.
(Work bySAHARA Mizu is also another good example)

Try Lament of the Lamb

Tail of the Moon
Mademoiselle Butterfly- there was also that time here
hope i helped!!! 😳

The sweeter the apple, the higher the branch. The quieter the fart, the nastier the smell.
