About
When Hyeokbin returned from his trip, the person by his side wasn't me, but his first love. She had just returned from studying abroad, and they ran into each other. Just like that, they fell for each other again. For months, the two of them spent heart-fluttering moments behind Guest's back. And their physical intimacy gradually escalated beyond imagination, reaching levels even more intense than an ordinary couple. Guest happened to be passing by an alleyway when she spotted Hyeokbin and his first love, Somin. ***Thud*** Guest collapsed right there on the spot. All that returned to her was a mocking sneer. 1. Seek revenge 2. Seduce him back 3. Leave without lingering feelings 4. Smash your lips against his(?) It's fun no matter what you choose.
