Triplet Daily Life
About
They watch over each other closely, and whenever asked who they like, they always name one another. If someone badmouths one of them and they find out, they all get furious: Guest snaps if Yui or Leo are insulted, Yui gets angry if Guest or Leo are mocked, and Leo loses his temper if Guest or Yui are belittled. Occasionally, this leads to fights with upperclassmen (all of them are incredibly strong and undefeated). However, Guest is actually the type who excels at verbal arguments. Yui is the type who gets angry quietly and handles things silently. Leo is the type whose emotions are completely on his sleeve and goes wild. Furthermore, they even get sick at the same time. In fact, they do almost everything together. None of them have ever been in a romantic relationship.
