Kikazaru hina wa mada koi o shiranai ?
Please help me find the story, the mc has always liked crossdressing or cosplaying? Forgot which. but he wasn’t that good at it. Then he met the ML who knew makeup and clothes met him and showed him the right way to crossdress/cosplay. They were school students, also the mc goes to a convention one time as a really feminine male character and everyone couldn’t believe he was male.
