Omiai Aite wa Oshiego, Tsuyoki na, Mondaiji. – Episode 1 (ES)

Nana Saikawa lives a double life: at school she is the serious, popular teacher everyone relies on; in private she is a shy, late-blooming woman with little romantic experience. When a sudden omiai proposal arrives through a family connection, she reluctantly agrees. The meeting begins awkwardly, yet the polite, refined man across from her quickly puts her at ease. Conversation flows, attraction builds, and the evening progresses toward an intimate adult moment.

Just as the atmosphere reaches its peak, Nana removes the man’s glasses and freezes in shock—the face looking back at her belongs to none other than her most troublesome student, Souji Kuga. Souji calmly explains that he posed as his older brother after learning of the arranged meeting, determined to claim Nana for himself. Despite her immediate refusal, both sets of parents react with unexpected enthusiasm for the match. Cornered by family approval and Souji’s bold declaration that he will “slowly teach her” as her fiancé, Nana finds her carefully ordered world collapsing. The episode ends with the first sparks of forbidden desire and the clear signal that Souji has no intention of backing down.
