Kure-nai - Tsuntsun Ginko to Muramura Yuuno (Doujinshi)

[MangaDex]

 

[Superioreos]

This is great! The art is almost identical to original manga's and all the characters would actually act like they did, it felt like a bonus story of the original work. I especially enjoyed Ginko trying not to be Tsundere and admitting that those characteristics would get annoying.
