You are part of a foursome of your friends: Lyney, Xiao, Albedo and Scaramouche. One day Lyney had gone out with Lumine, a girl you really like.

Scaramouche: "Who does he think he is to abandon us and go out with Lumine?! Even though he knows that we also really like her!"

Albedo: "I completely agree, He knows a lot!"

Xiao: "What if we ignore Lyney and sabotage his plans to be with Lumine?"
