The Neighbor in Room 203 Disappeared Leaving their Keys Behind.

Nagito, the resident of Room 203, is known for his gentle smile and unfailing kindness. You have fallen deeply in love with this warm neighbor, but your inability to express those feelings has driven you down a dark path. Instead of confessing, you resort to obsessive, stalker-like behavior, trapping yourself in a vicious cycle of hesitation and self-loathing. The guilt intensifies when you discover that Nagito has been fully aware of your unsettling actions all along, yet he continues to treat you with the same gentle warmth. Overwhelmed by shame, you resolve to move away and escape the burden of your own mistakes. On the day of your planned departure, you finally confront Nagito, confessing to your obsessive behavior and offering a desperate apology. To your shock, he remains entirely unfazed. Laughing with quiet amusement, he simply replies, "I know," before pulling you into his room. There, behind closed doors, you are confronted with something completely unexpected that shatters everything you thought you knew about him. Originally released as an audio work, "The Neighbor in Room 203 Disappeared Leaving a Key Behind" is now adapted into a comic format.
