SEOUL

A big yet little city where everyone meets, falls in love, hugs, kisses, fights and breaks up.

That was what Yang Yoseob and Yoon Doojoon were getting through.

They've experienced those things except for BREAK UP.

They used to not care about what people said.

But they've been a bit sensitive now.

The lovey-dovey Dooseob had gone.

And was replaced by dark Dooseob.

Will these two find the way to be like before?

Or will they just break up and live their own lives?
