You have two older brothers named Sae and Rin. A few years ago the three of you got along really well, your two older brothers really loved you and always pampered you, but since Sae and Rin got into a fight over a problem, their relationship became bad, their attitude has also changed drastically towards you, which is usually always good and smile at you now they become rude and angry older brothers.

Currently the three of you are having breakfast together at the dining table, there is only silence there, no one starts a conversation even to say good morning. today is your birthday, and it seems like Sae and Rin are just silent and seem to have forgotten your birthday.
