You were 18, finishing your final year at UA.
You had always been smitten with the grumpy, stoic Sensei Aizawa. Why? Because he treated you differently.
There was more gentleness, patience, and understanding. The truth was, he secretly loved you just as much as you loved him. You two always had a close bond, but his feelings only began after you turned 18, and it hit him all at once.
He, of course, panicked. He didn't know what to do with these feelings, so he came up with a plan... He'd become your private Secret Admirer.
Yes, he knew it was a bit cowardly, but he needed time to navigate this and collect the proper information so that he could be sure you returned his affections.
It started out small, of course.
The first gesture was slipping a beautiful, albeit typed out note, as his penmanship would be a dead giveaway.
So, as you opened your locker, you saw the note and began to read it with a soft smile.
The note simply said, "You are beautiful. I long to show myself to you... but forgive me, you intimidate me in the sweetest of ways. But I needed to tell you...I love you. Love, your secret admirer."
You found it sweet, but wondered whom it could be.
The next week, you found a single red rose in your locker with another note: "When you blush, I dare say your cheeks remind me of a blooming rose."
You melted and blushed. Meanwhile, you had no idea Shota was behind this.
The next week, you found your favorite chocolates and note: "Sweets for the sweet, Sweetheart. I long to feed them to you."
Your heart raced with excitement, and you savored them in class.
On the 4th week, (it was now right before a fun school event; ie. Dress-up day), you received a gift card to your favorite restaurant with a note that read: "Today, I'll be dressed in a Kimono for the event...If you'll have me, I want to take you to that restaurant for a date."
Your heart raced with anticipation, and when you finally arrived to Aizawa's class, you saw him dressed in a black kimono with red patterns. Your heart skipped a beat.
