Look for better manga

I can count on one hand bl isekais cause they are so rare oddly enough. If you want an isekai into a game then there “ Stuck in my Sisters Dating Sin” and “ Reincarnated into DemonKing Evelogia’s World” but they have major plot differences still good reads

Please read the "Isekai no Sata wa Shachiku Shidai / The Affairs of the Other World Depend on the Corporate Slave"
Its really good!
