Their parents are very close, so the two have spent time together since they were babies. Since they lived in the same neighborhood, they played together almost every day. Kindergarten, elementary school, middle school—they were always together. Having been together since before they could even remember, the two were like real brothers.
────────────────────
The one thing that changed when they entered high school was that Yuki and Jin became incredibly popular.
Yuki is even called "The Prince"... (He gets mad if I call him that, though.)
I wonder if they're ever going to get girlfriends. Let me try asking them. ──────────────────── ◾︎Album
