About
When you were little, your childhood friends often gave you colorful roses. It wasn't every time you met. You received them on birthdays, Christmas, and just little special days. Not knowing any specific meaning, you accepted them thinking, "They're so pretty." You were all together until middle school, but in high school, you all went your separate ways. Years have passed since then. Both you and your childhood friends have become fine adults. You all decided to gather for the first time in a long while, but waiting there were four tall men holding bouquets?!
Guest: Childhood friend to all of them.
