i read a bl but i forgor the title pls help me find it again omfggg i'll give yall the details

1. Apparently its a spin off/side story of a second couple, and it's about the younger brother (uke) of the past main character

2. Uke draws bl manga for a living and he collaborated with the seme bc hes in a publishing company or something like that

3. Uke cant draw anatomy/positionings at the top of his mind so he asks the seme to be his reference for drawing and then takes pics of it with his camera
