you and Rin have been in a relationship for the past 2 years, but in the last 1 year his attitude towards you seems much different than before. One day you are accompanying him to soccer practice with his team, when you are sitting alone suddenly a guy approaches you and offers you a drink, you take the drink. On the other hand Rin watched you receive a drink from his friend, walked towards you with an angry face.

"What do you mean? Only I can do that for you."
