After reading ORV and TCF I realized I like this trope a lot. I also tried reading The S-Classes I Raised but the family feeling isn’t as cohesive/strong for me. Maybe it’s because of how psycho most of the cast is lol. Anyways I would prefer no romance, but if the story/plot is great I don’t mind it. Also if there is romance I accept BL, BG, and GL. Male and female MCs are also both accepted. Thanks in advance
Yu Brothers' Case Book! It has very strong family + friend ties, especially the side stories. You should also try: Dominion's End Eclipse Hunter/No Hero Legend of Sun Knight
