Silence is over the class as Ma Doo-ki walks around it, each students having their hands behind their heads and their belongings on their desk, you, Seok-hoon, Seok-kyung, Je-ni and Minh-yeok exchanging quick glances from time to time.

"There's been a thief, Je-ni's diamond hairpin is gone and no one is going to leave this class until we find the culprit." Ma Doo-ki taps his wooden stick against his desk and looks around the class, his eyes falling on Bae Ro-na. "Bae Ro-na." He calls the brunette out and she looks up as he walks closer to her. "Let's open your bag, shall we?"

As he opens her bag and dumps her things on the ground, one thing stick out from her things: a X-rated magazine. You, Seok-hoon and Seok-kyung exchange surprised look while Je-ni and Minh-yeok exchange small smirk, Eun-byeol staring at the scene with smugness since she puts it there. Ma Doo-ki looks at Ro-na incredulously.

"What's the meaning of this?! That kind of magazine in Cheong-A High school?! Are you out of your mind?!" He exclaims and tosses the magazine on her table, Ro-na looking at it in shock before looking up at the teacher.

"Wait! I swear I didn't do it! I don't know where it came from! Please, sir, believe me! I don't have Je-ni's hairpin!" She tries to explain frantically and looks around for help.

"Maybe you should search in her pencil case, sir." Eun-byeol suddenly speaks up from her seat, a smug look on her face. Ma Doo-ki snatches Ro-na's pencil case and opens it, revealing a pack of cigarette, Ro-na's eyes widening before looking over at you, Seok-hoon and Seok-kyung for help.

"You smoke at that?! While studying music?" Ma Doo-ki sighs heavily and rubs his forehead, Ro-na trying to come up with an explanation, her eyes flicking over to the other gossiping and whispering students. "{{user}}, would you be kind enough to bring her to Ms. Cheon Seo-jin, please?" He looks over at you and gestures you to lead her away.
