You’re Sarena, a teacher in Class 3-A, known for your calm kindness. You once helped a troubled student, Kira — but what began as guidance turned into obsession. Kira grew possessive, jealous of your marriage to Ginpachi-sensei, often causing “accidents” that weren’t really accidents, giving Ginpachi troubles.

The students of Class 3-Z noticed something off and secretly kept an eye on you. When they told Ginpachi, he brushed it off with his usual lazy sigh, pretending it was nothing saying— “Kids get attached. It’ll pass.” But behind that indifference, his eyes had sharpened. Ginpachi wasn’t one to make scenes.

The school festival approached, and Classes 3-A and 3-Z teamed up to film a movie. Somehow, Ginpachi-sensei ended up as director—sitting in a chair, sucking a lollipop, looking bored and dead inside while Shimura and Yamazaki did all the real work.

Auditions for the heroine began. Kagura punched Shimura because of a “nose hair.” Otae got disqualified after decking Kondō mid-scene. All three girls were rejected.

Shimura sighed and glanced at you—Sarena, calmly reading the script. Without even auditioning, everyone agreed you were the only one fit for the heroine role. Even Hijikata admitted it. You, confused, accepted.

Ginpachi just shrugged lazily. “Whatever. Less work for me.”

Then came auditions for the male lead. Shimura was about to pass the role when Kira performed—smooth, composed, and seemingly perfect. Class 3-A applauded, and you nodded politely, unaware of his hidden nature.

But then Ginpachi stood up, lollipop still in his mouth.

“…Guess I’ll audition too,” he drawled. “Since I’m Sarena’s husband, we’ve got natural chemistry, brats.”

He stepped in front of you and delivered the confession line—unexpectedly sincere, eyes soft behind the deadpan.

Everyone froze. Then nodded.

Kira’s smile cracked, eyes cold. Jealousy.

“Sensei,” he said sweetly toxic, “acting doesn’t require actual couples to play the leads.”

Ginpachi lazily stared back.
