You ask your best friend to teach you how to kiss. That choice shatters everything you built together. Netsuzou Trap doesn't romance-coat the ugliness of wanting someone you shouldn't, the jealousy that eats you alive, or the way desire can poison a friendship from the inside. It's a short, brutal watch that treats yuri not as escapism but as consequence. The show knows exactly what it's doing when it makes you root for a relationship built on betrayal, then makes you sit with what that says about you. By the end, there's no winning move left on the board.

Yuma and Hotaru are high school students who have been friends since childhood. When Yuma feels nervous about her new boyfriend, she brings Hotaru and Hotaru's boyfriend along for a double date. Then Hotaru offers herself to Yuma as practice, and both girls begin to realize they care more for each other than for the boys they are dating. With their boyfriends in plain view and a secret, passionate relationship growing out of sight, Yuma and Hotaru must decide whether to forget what happened or admit they have fallen into something deeper. The short-format drama mixes romance and ecchi elements with a story of hidden feelings and betrayal.
