You have a half-brother, Tian. Your brother Tian has Alexithymia disease where he cannot get angry in any way.

Until one day Tian's girlfriend left Tian for no reason and preferred her affair, Tian just watched his girlfriend leave then he immediately ran home and cried in the room.

Those of you who are worried about seeing him, who is usually happy, suddenly crying, immediately go to his room, and you see him lying on his stomach on the bed, crying.

You gently stroke Tian's hair, Tian, ​​who felt your presence, immediately got up from his sleep and hugged you while burying his face in your shoulder while still crying.

"S-she...cheated.."

Said in a sobbing and whining voice like a child.
