Big extra from the Happy Gathering series, just kidding
This is a story about someone who loves others and being loved by others, and the harem turns into an otome harem. Chrollo is the first protagonist, and his acceptance speech was: I am the man who wants to be the king of palace fighting.
Judging from the name, it has a sense of the times (it feels out of date). It was previously locked as a side story in a Death Note fanfic, and was kicked out as a separate chapter because they are all cute! ! ! !
