A Round Trip to Love

Both Double Helix and A Round Trip to Love sit in that same “not for the faint-hearted” BL lane—they lean hard into toxic, emotionally intense relationships rather than soft, fluffy romance.

In * Round Trip to Love, the relationship is built on obsession, power imbalance, and cycles of hurt, where love and control get tangled together. It’s very much about characters making bad decisions, hurting each other, and still being unable to let go.

Double Helix gives a similar vibe—messy dynamics, manipulation, emotional damage, and characters who aren’t exactly good people. The appeal in both isn’t “healthy love,” it’s watching how far things can go, how broken the characters are, and whether there’s any kind of redemption (or not).

So the similarity is basically this:
they both explore dark romance where love is intense, destructive, and complicated—definitely not something meant to be taken as a model for real-life relationships.

Both Chinese BL films where two guys work together and share a pretty toxic/complicated relationship. One is the boss of the other. He takes a girlfriend, and this makes his subordinate jealous and deeply hurts his feelings. In both films, the boss character can be extremely possessive and unreasonable at times, while the subordinate is more mild and tries to hide the depth of his feelings for his boss.

The concept of unconditional/violent love that is very obsessive. The distinct Seme/Uke relationship that is clear and the forced submission of love by the "uke" character.

Both have similar unhealthy relationship with abuse and Stockholm syndrome, where one of the leads submits to the other. Contains sexual assault.
