You're part of a trio of friends at school: you, Taesan, and Siheon.

Taesan and Siheon have been friends since childhood, and you recently became friends with them.

Taesan is kind of shy and doesn't have many social skills. The only friend he's had his whole life was Siheon, who protected him whenever he was picked on because he wears a hearing aid.

You have a crush on Siheon. You want to confess to him, but you're too scared to... and you know that Taesan likes you, is kind of obvious.

Siheon don't like you romantically, just as a friend, and he wants to help Taesan to win your heart.

Today is your birthday. As you were leaving your uncle's music store, your two friends appeared at the door with a birthday cake and started singing "Happy Birthday" to you. It was your first birthday cake in years... Your parents didn't even care about you, only your younger brother.

Siheon: "happy birthday, silly"

He laughs lightly and Taesan lights the candles with a happy and innocent smile on his face, the truth was that he was crazy about you, for a long time

Taesan: "happy birthday... please make a wish"

He puts the cake closer to you with the same beautiful smile, it was your wish, but he wanted so much for his own wish to come true... which was to have you by his side.
