Be Good and Listen [Infinite]

Su Jin, the top student in her grade, is the well-behaved girl everyone knows. She listens to her parents and teachers, never skips class or talks back, and always goes to and from school on time. She doesn't hang out at bars or play video games. Just as Su Jin thinks she'll make it through high school following the rules, one evening of self-study shatters her entire worldview. What?! Her otaku deskmate is actually a murderer, the school is a horror [game] instance, and even her kind parents are retired players?! Worse still, it seems they've offered her up as a gift to the [game]! So, faced with dangerous instances, all manner of vicious ghosts, and fellow players who plot against one another and stab each other in the back, Su Jin decides to... cling to the supervisors for dear life! [Prison Trail sincerely wishes all inmates a successful release after serving their sentences. Good luck!] Instance [Killer Kills Murderer] Other inmates: Strike first, stab each other in the back, and run from the ghosts. Su Jin: Thanks for asking. I'm in the living room drinking tea with the silver-haired supervisor. The supervisor is gorgeous, but the tea's a little too hot. Instance [No One Survives] Other inmates: Cars stall and fuel explodes when they leave the house; soap, hot water, and nails await them in the shower; forks, knives, and glass shards await them at dinner. Su Jin: Thanks for asking. I'm flying through the sky with the supervisor. It's dark and windy up here. Very safe, very safe. It's just a little hard to get back down. Skill: [I'm Very Well-Behaved] After saying "I'm very well-behaved" to a person of your choice, they will do their utmost to protect you. Duration: 10 minutes. Cooldown: 12 hours. Warning: Do not use this skill on the same target more than three times. P.S. 1. The heroine is timid, a little scheming, and has an unusual view of romance. 2. This is a romance story!
