I changed the tags from 4boys to 3boys + 1other due to ambiguity over Nono's gender. Nono is almost always a girl's name in Japanese (see this name website), and Shoko uses -chan for them, which would be unusual if they were a boy. I think it's likely they were intended to be a girl, but I'll leave the tags as is unless someone more knowledgeable wants to change them.
