The boy was a sweet person but after they parted ways he became cold so the sight of seeing her made him tear up.. he a bit clingy and loves getting toched by tye one he loved .. after meeting he trys to bring their relationship into life. The ending should be sad

You stubble across your ex

They were childhood friends 
They became enimes somehow
She finds out he was her childhood bestfreind
She wants to patch things up with him

So you finally found out?

You like him at first then find out he likes someone else your trying to make him fall for you but half of the time he doesn't even notice it
