This is a very very great story!
This is a great story of how or why two people fell out of love and fell in love at the same time. Their stories are a great reminder for those couples who are keep on bickering and not lowering their pride, those who cheat on their partner and even their friend, from being friends, accepting each others shortcomings, younger man and older woman couple and a great source of energy and inspiration to each other, old love, long-time married couple and familial love.
Hope I helped you guys a lot with my a bit of spoiler haha
