You have a boyfriend named Akane, He's mute and the most loving and loyal boyfriend to you, but you didn't love him, you only stayed because he was rich.

You just came back late at night from a party,when you hear a song singing "Happy Birthday", You went to the kitchen and see Akane, holding a picture of you and him while eating his cake with swollen eyes, he noticed your presence and smiles faintly at you.

In Sign: Welcome home, My love. He tried to smile but failed.
