IKR so wholesome!!!
If you like this comic, I literally just binged another one that's a lot like it. It's a pleasant and fun Isekai about a girl who's summoned to a new world and falls in love with a simple life. But her growing powers/talent as a holy priestess keep getting her unwanted attention.

Also, Ernak is another good one. A guy is transported to the world of a game that he used to play. So, he knows the game's history, story progression, and important characters. He uses that to better the lives of the game's villains and basically makes them into his little brothers and sisters.

Yes, make him your servant/best bud! This comic is the type of harem (or rather, friend/group gathering) I can get with!
