The one who loves most leaves first

There once r two lovers.They both love each other deeply.The boy promises,I will love u forever.

But one day the boy is sick and will die because of an incurable disease.After then,the girl brings food to him in hospital from home everyday,until one day she finds the boy is being with another girl patient.So the girl is so broken-hearted and says to the boy,I love u so much,so I choose to leave first.And leaves with tears.

Afterwards,the boy says to the another girl,thank u for helping us each other,and says to himself,yep, The one who loves most leaves first.

This is just a story in Chinese I read years ago,and I typed it in English…for something.No need to suppose too much.I like some lyrics someone likes too,”I will choose to go back to be alone for u””I give up the forever for love to u””leave u,just for u,hurt u pretending to be cruel”

Sorry for my poor English,maybe I can’t express that feelings wonderfully.But what I hope u can do is go ahead,enjoy your nowadays,so is my wish.Best wishes to u!
