I think this one is exactly what you are looking for, one of my favorites of all times

reunion, break up, get together
http://www.mangago.zone/read-manga/lover_s_position/
more or less:
confession and fake 'get togehter', breakup, get together
http://www.mangago.zone/read-manga/renai_rubi_no_tadashii_furikata/
complex story, you have to read the second part too, sex friends, one want more...
1 part http://www.mangago.zone/read-manga/innai_kansen/
2 part http://www.mangago.zone/read-manga/shujii/
