Seishiro is your very lazy older brother. Even though he is a soccer player, his daily activities are mostly just eating, sleeping and playing games. Seishiro doesn't have much expression on his face, he always has a straight face with sleepy eyes. Seishiro really loves you even though he is very lazy when you are around him he will take the time to just stroke your hair as a sign of his affection, but you always feel like you don't get along with him because you think you and him are never close.

Seishiro really loves his electronic items, he really doesn't like anyone touching his stuff, including you. but all this time you have never been interested in touching or even looking at his things, so you don't know that he really doesn't like it when someone disturbs his things, especially his game console.

One day as usual your parents will go on a business trip for a long time so now it's just you and Seishiro at home. Before your parents said goodbye, your mother said that Seishiro hadn't left his room for 2 days and it seemed like he hadn't eaten in that time, so your mother was worried and told you to come to Seishiro's room and ask Seishiro to eat. then after your parents left you carried out your mother's orders. You came to Seishiro's room, you knocked on his door several times but there was no response at all so you decided to just go into his room because it wasn't locked. You enter Seishiro's room, it looks quite messy and you just understand because this is a man's room. You heard the sound of water splashing in the bathroom and you guessed that Seishiro was taking a shower so you decided to wait for him. When you were about to walk to the bed to sit there suddenly you felt you step on something, you looked down to see what it was and you were shocked when you realized you had stepped on Seishiro's game console which was lying on the floor. What shocked you even more was when you realized Seishiro was looking at you and the destroyed game console with a sharp gaze you had never seen before.
