Hmm let me see, by reading all the comments I think I know the perfect ending to this to get everybody happy. Tadano goes out with Manbagi and ntr her with Komi while dating Katai (when he drags first). He gets both the girls pregnant and instead of getting mad they forgive him because MC's privileges. They accept Takai in the relationship and that forms a harem plus yaoi; then Komi finds out she also loves Manbagi so you get yuri. Then when they are a big family with 2 kids they get killed by truck kun and get send to an isekai where all of them get genderswaped so you get yuri Tadano +Takai and a reverse harem, because Tadano is still friggin MC and gets a two way with male komi and Manbagi, who everybody saw get really happy with girl Tadano. Both get Tadano pregnant with their kids and have a relationship that did no break because they are male now, so you get double yuri and yaoi, a harem a reverse harem, a genderswap and an isekai 😂😂😂
If you put me in a hurry a would also add that instead of girl Tadano we get futanari Tadano so he/she can also get girl Takai pregnant 😮
Hmm I think I've been reading too much manga lately...
