Taeyeon must met her ex  love, Sehun again.

It because her brother, Baekhyun asked her to find out what happened with Sehun.

Sehun is a member of EXO, the kingkas group of our school.

But about 2 weeks ago, he got a fight with his group and leave the group.

The other members started to hate him, especially Kai, but Baekhyun felt something weird happened to Sehun.

Taeyeon felt that too, she heard Sehun broke up with Krystal.

She still can't believe that. She still remembered how the way Sehun kissed Krystal that broke her heart so badly.

She knows that Sehun love Krstal so much..

But why he broke up with her?

And why he leave EXO and be a quite boy like now?

Taeyeon told herself.

She must find out about what happened to Sehun..

Must...
