He was just a guest.

A guest who'll stay for the whole summer.

But I didn't expect the things happened.

My group of friends being friends with his group.

Him being together with one of my best friends.

And them breaking up...

My whole summer is an unexpected roller coaster ride ;

'cause

there's us.

Falling in love with each other.

And THAT happened.

I then wished I didn't became friends with him on the first place.
