Hi,
I remember reading a dj of bakugo x deku (boku no hero academia) but forgot the name. The plot was kinda like this: arranged marriage, bakugo was from a dragon tribe I think, and deku was the bride, deku was an omega (and used bakugo clothes to build a nest - there was a scene were bakugo asks his mother about his clothes and she says that deku needs them more than him), some age gap (deku was older, bakugo was underage when the marriage happen), took some time until he was able to smell deku's hormones. Please help ╥﹏╥

Hi, I need help finding a manga that I read ages ago. I remember that there were many princes and many candidates for concubines. Every night each prince chose one to spend the night. I remember that there was magic in this world and that there was a kind of seal on at least one of the candidates so that she couldn't use magic. This same candidate in one of the chapters removes the seal so she can cast a spell against the protagonist, then quickly puts the seal back on with someones help. I also remember that the spell did not affect the protagonist but the king and it was one of the candidates who, under the pretext of being called by one of the princes every night, helped to cure the king. There were also some kind of tests to choose the best candidate for each Prince. Im not sure if it is isekai. Thank you ╥﹏╥
