I like this story. It reflects the reality some people have to face. And reality is sometimes sad and not what we want. Simply moving somewhere where your love can be accepted is often not an option for numerous reasons, finances, friends, and family being among them.
I think it's hard for people to accept that. We want them to be gay and happy together. But their lives are they're own. There are some works of fiction that use fantastical elements to create an engaging narrative, and then there are some that simply holds a mirror to reflect the values of the society they're written in, and this story is the latter
Arranged marriages are a thing. Marriage and children are still seen as the end goal for a happy life. Sometimes relationships you don't want ending has to end because society demands it. The story is sad, because those expectations lead to sadness in the people who are expected to follow them. Not everyone is a revolutionary, no everyone can yell, screw you, to the expectations thrusted on them. They accept it to live and adapt, and it's sad but it's also life. No matter what you choose to do, you have to sacrifice something, and be there to live with the consequences
