I haven't really played the game yet (just 10 minutes or so in), but reading the comments here, I feel like people are stupid.
Having Yuri doesn't make the game NTR/NTS and it doesn't make the protagonist a "cuck".
I feel like the game is heavily story based, which is nice. I'm not here to collect girls every 5 minutes. Harems are nice and all, but certainly not necessary, so feel free to write the story however you want, independent of the comments other people make. I'm certain I will enjoy it.
