10/10 recommend reading “transmigrated-into-a-female-oriented-card-game”. Harem is definitely an off putting statement but there is genuine development with all the characters and reason for why the main character and they would fall in love. I’ve seen that you praised TCF with “if-you-dont-become-the-main-character-youll-die” and I would say that the dedication to each character is absolutely parallel. I would also suggest reading “show-me-your-stats” that is on this list. Give the manhwa a try, they’re both a good form of the story. 

Both have thoughtful characters and they deeply care of the people around them. 

As for a story not on here, “extra-works-hard” is a beautifully detailed story.
