Kinda similar story
Omg it is similar to that but the art was wayy different although maybe im having false memories
The uke was never a tsundere

This one is also similar but not smutty
Yess but i certain its not that, the artstyle was giving very smutty doujinshi x pretty
Tysm for helping me though
It's a master x servant type? Where they were childhood besties and the seme is a butler/bodyguard and the uke is princely? He's like from a rich family and seme and ukes parents know each other well. IT HAD AMAZING ARTSTYLE like really pretty! It was also similar to this storyline
