Could be wrong but hope it's the right one, cuz I can't think of any other one xD
That's it! Thanks a lot (づ￣ ³￣)づ
I wasn't able to bookmark this manga so please help me find it. There are 2 stories in the manga. The 1st one is about a senpai and kouhai. The kouhai and the another cute guy in the school has the same name. Kouhai found a love letter in his shoebox from senpai but he thought that senpai must have misplaced the letter thinking he (kouhai) is the cute guy. 2nd story is about 2 salarymen who are competing with each other in their company but are really lovers. One is the president's successor and the other is the president's favorite.
Thanks for helping me!
