You were 20 years-old and the youngest Sensei to work at UA. You no sooner graduated, when you returned the next year as a Sensei, and they hired you on the spot.
You were the top of your class, a model student, showed empathy, patience, kindness, and great logic and reasoning skills, and also had connections with Toshinori as your father.
They obviously had to do the preliminary interview for protocol, but Nezu needed no time to deliberate. Especially when you presented what you'd be teaching.
You would bring Villain Psychology to the table- the newest subject on the curriculum. Nezu knew this was definitely an opportunity he couldn't pass up.
Your argument was simple: Know thy enemy. Never mind the fact that you also did villain reform work.
Nezu, being impressed with your credentials in the few months since your graduation, agreed, but asked you to get guidance from your former Sensei's as well to help show you the ropes and get together lesson plans.
Shōta, the Sensei you loved and were very close to since you were his student, took you under his wing- no questions asked.
You two were dating at the point, of course. You still kept it quiet for now.
But now, you were 20, had been married a year, and it was the beginning of your second year of teaching. You had gotten into the swing of things and loved your job. You taught 6 class periods (a full day) of all ages from Freshman to Seniors.
You were also hit on quite a bit by the older students, which... sadly was to be expected, but it was unnerving nonetheless. It pissed Shōta off to no end. So, he'd often stand watch in those classes to ensure everyone was on their best behavior.
Today, Shōta came in to keep watch, immediately making the class become more focused, when you lit up. You were feeling a bit brazen, so you sweetly spoke in greeting, "Hey, honey! You make my whole week!"
The class "awwww'd" at your seemingly innocent comment, and Shōta blushed, smiling faintly- not one for PDA, but slowly getting used to it.
That's when you whispered into his ear, "My H-O-L-E W-E-A-K." His eyes widened as he choked on his coffee and went beet red before you pecked his cheek and went back to teaching, leaving him a flustered mess.
He had to sit down and hide what your comment had just done to him. Some of the students smirked and giggled, knowing you likely said something naughty, but not knowing what.
Meanwhile, you couldn't help but smirk inwardly, knowing he would get you back later after work.
