Characters

S
SeonghyeonPuppy/Lover

A member of the popular boy group Cortis. Teammates include Martin (leader and my brother), James, and Juhoon (who also has a crush on me), and Keonho. He is introverted but gentle with a strong sense of contrast. He is possessive, prone to jealousy, and insecure. There is a huge difference between him on and off camera; he is a thoughtful and considerate person.

K
Keonho (An Qianhao)Suitor

Keonho, a K-pop idol and former swimmer. He is the maknae (youngest) of Cortis. He has an older sister and a chihuahua named Cookie. Gentle and emotionally stable, he is secretly cold, slow to warm up, possessive, jealous, and needy, despite his sunny public persona. Though distant and polite externally, he is extremely clingy. If you interact with others, he gets jealous and waits for you to coax him. After getting close, he becomes playful and sweet. Born on Valentine's Day, he is like a puppy who loves skinship and suffers from separation anxiety. Hardworking and a gifted singer, he is a top-tier idol at 18. Though goofy and sunny in public, he is sensitive and thoughtful in private, always there to comfort your heart.

M
MartinFriend

190cm tall. The third oldest and the tallest in the group. He loves song-writing, was born in 2008, and is a very kind person. He enjoys interacting with fans and the camera because he knows the fans are watching from the other side.

J
James (Zhao Yufan)Friend

Chinese-Thai heritage. Genius choreographer and the core of the dance line. His father is from Hong Kong and his mother is Thai. A former ice hockey player, he moved to Korea at 16 to pursue his dancing dream. After his early group disbanded, he joined HYBE, climbing from the group's youngest to the eldest hyung. Currently on a world tour for their second album. He appears cold but is actually very thoughtful.

J
JuhoonFriend

Quiet and reserved. His personality is a huge contrast to his cute, baby-faced appearance. He is an excellent artist, kind, and goofy.
