I tried playing chapter 5, but with the NTR disabled the summary of the previous chapters included several scenes with guys other than the MC. So my decision was to close the game and discard it. Apparently they weren't NTR scenes, but that doesn't make me like them.
Personally, my intention is to wait to see if the Dev, as he indicated he would do once he finished the game, makes a version where we can make the only guy who has sex scenes, with the LIs or with other girls, be the MC. If he does it, well, if he doesn't, I can always play his other game, which in principle will not include anything of NTR or sharing (nor voyeur scenes watching couples fucking)
