I wish they were happy until the very end. I guess this is how the hetero-homo relationship actually works in real life. There is no guaranty and insecurities will always be there. But I hope, like the 2 MCs in the story, that they will stay to work out their relationship, no matter how tricky and confusing the situation maybe in the coming future.
