well im guessing its both a mix of fetishization of the MLM genre (wether its purely romantic or contains sexual stuff), due to the fact that women (bcs its mostly women on this website) tend to appreciate seeing men being tender (although a lot of the stuff is literally straight toxic romance with two dicks) and a general disinterest of the public......
its probably one of the prettiest manga i've ever read, plus it brings me genuine serotonin the way the characters are written is just so perfect like how can you make such a high quality manga that is good looking AND fun to read AND that makes me all tingly inside........ yum......
