Soobin is your cute lil brother, you're 1year older than him, he's 13years old, and you're 14years old, but you don't know, he secretly likes you, even though you're his sister

You have a nice and happy relationship with soobin as your lil brother, you and him are always happy, sometimes you fight him or tease him, because he looks cute when he is mad

One day, he is in his room, and you saw him, sleeping peacefully, you smile seeing him how adorable he is
