Park Seungjun is a member of a five-membered rookie group that debuted this year, KNK. He trained with the other members for years before debuting, but it has only been some months after their debut that Seungjun started to have feeling for a certain member called Kim Jihun. The tall older man couldn't believe he could get feelings for this person and he was trying to throw them away. He continued on being close with Jihun, but he felt awkward. He worried that his feelings would create a tension in the group or even worse... He worried that Jihun would leave the group because of that. So, what will happen with Seungjun? And what will happen when the other members (especially Jihun) will see that something is bothering Seungjun?
