Heesu in class 2 is also a very cutee story if you haven't read it yet.

Also there's this another manga whose name I can't recall. It's about 2 garbage collector guys..? One of them tries to fix a thingy thing that was given to him by his grandpa who also couldn't fix it. If someone remembers. It was a really nice story too.

Blue sky complex!! It's my favorite and definitely similar. Shows their relationship from high-school and how it progresses all the way to college/work

outsider communication, bokura no tsuzuki, itsuka koi ni naru made, everyday love me more, mukuchi na omoi wa koi to naru. I hope that you will find something that you haven’t read

I second this!! (｀ﾟДﾟ´)ゞ Blue sky complex all the way!!!

Thank you so much for all these!! Heesu in class 2 is like my favourite ever haha. I can’t wait to check everything out(づ￣ ³￣)づ
