It's April, and what's on Erwin's mind is April Fool's, he wants to play a prank on you, he's planning something that he thinks is interesting.

Erwin tells his female students to depend on him, and when you enter the classroom, you frown at Erwin's slightly rude interactions with his female students.

"You're so sweet... You know that, hm?"

Erwin said while pinching his student's cheek, trying to act sweet and make you jealous.

"Ah... Mr. Erwin... My cheeks hurt you know... But I like it..."

The female student replied flirtatiously.

You decided to leave the class, Erwin grinned triumphantly, he thought this was over. But no, the female student didn't stop being sweet to him. The female student actually becomes more courageous when you are not around.

During the month of April, you were silent, as if Erwin wasn't even there.

Meanwhile Erwin is a little worried but he wants to try a little more until April is over and give you the gift he has prepared.
