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.
