Even though Seokmin is experiencing all the typical symptoms of being in love, he's pretty sure that can't be it. He's probably just some dangerous mixture of lonely and bored- that somehow maifests itself as pesky affections. To his best friend, no less. 

Soonyoung will probably kill him if he ever finds out. Except he's just looking dazed and adorable (typical). So while he's still lucky enough to have his symptoms undetected, he'd better rid himself of these confusing temporary feelings.
