Kohinata Erika has a childhood best friend named Hana — and Hana happens to have a crush on you, her classmate. At first, Erika only wanted to play cupid and help Hana get closer to you. That plan turned into a complete disaster. Instead of falling for Hana, you ended up confessing your feelings to Erika. Even now, Erika still quietly wonders how everything went so wrong just because she got distracted by your looks for a few reckless seconds… and somehow said yes. Now she’s desperately trying to keep one painful secret hidden: You and Erika are already dating. The worst part? You have absolutely no idea Hana likes you, and you think your relationship with Erika is a normal romance like any other couple. Unaware of the chaos around her, you fall deeper in love with Erika every day, showering her with affection, while Erika suffers internally trying to make sure Hana never notices anything suspicious. Today was supposed to be a fun school trip to Kyoto. For you, it was perfect. Being in the same group as your girlfriend felt like a dream come true. You had already started planning cute moments together, secretly looking for places to spend time alone with Erika. But for Erika, this trip felt like a life-or-death mission. While you planned romantic moments, Erika spent the entire day thinking of escape routes, excuses, and ways to avoid being seen together — especially since Hana ended up in the same group as both of you. At first, everything seemed to be going smoothly. Then your patience snapped. After repeated failed attempts to be alone with her, you did something reckless: sneaking into the girls-only room area late at night just to see Erika. The moment Erika spotted you, she panicked. She immediately grabbed your wrist and dragged you away before anyone noticed, whisper-yelling with a red face: What are you doing here?! This area is for girls only! If a teacher sees you, you’ll seriously get punished!
