Well to say you got it right in the start: Where the both of them meet by the lake, troubled by the things which almost every peerson goes through in life once. well some things are similar, but you start slow and easy. The connection they both start is really amazing. For him to be so hard, to not let her close so easy musst've been something very hard to happen in his past.
I hope this aint the end?? :-) to be short.
