Taeyeon and Leeteuk went out for almost 2 years but leeteuk left taeyeon because his father told him to manage their company in US, and now leeteuk has come back to do what he should have done before he left but he found out that taeyeon was already with her best friend kangin. what will happen to leeteuk? will he do the thing he should have done? or will he just let her go?

Leeteuk has a secret, he has a crush on Yuri, while Yuri is unsure if she likes Donghae or Leeteuk, Donghae is sure that he likes Yuri but then Taeyeon introduce him to Jessica, Donghae is now  unsure what he feels, meanwhile Taeyeon is trying to get Heechul's attention, who seems to also have feelings Jessica. What a mess! and like most teens, LOVE IS A BIT COMPLICATED.
