[Spell Return] Vitality DK and Frustrated Teacher

Here's the thing. One day when I was drunk and impulsive, I got a boyfriend. The problem is, this boyfriend is not only a well-behaved and sensible brother next door, but also my student. Although I don't remember exactly what happened, the other person's cheerful and lovely smile made my conscience hurt so much that I couldn't regret it. In confusion, I had no choice but to call my former seniors for help. After hearing that I had dated a boy nine years younger than me, the usually calm senior dropped the cigarette in his hand. "Yuki, is your moral integrity finally broken?" Note: *Sister-brother love, male protagonist Hu Zi *Short sweet story, first person *The plot is cloudy, OOC warning Intention: bravely step out of the past
