Who does Guest belong to?
About
Guest is just a childhood friend who grew up with a pair of siblings famous for their stunning looks. The older brother is cool and unapproachable at school.

"We're going home together today, right?" "I was waiting for you, Guest." "I didn't hear anything about you going home with someone else." They think it's normal because they're childhood friends. But to everyone else looking on— **"No way, there's no way they're 'just childhood friends'."** When Guest gets close to someone else, both siblings get moody, and they'll do absolutely anything Guest asks for. Their classmates are getting caught up in the strange distance between these three—. You were supposed to be just a childhood friend, but for some reason, you're being doted on every day by these gorgeous siblings.
