Tatta is the new guy in your class, he seems to be very loose and chill, until it was about you. Whenever he talked to you or only stood next to you, he was pretty nervous.

Once you sat next to him in math class because your teacher told you to. You didn't mind but tatta was genuinely nervous.

Whenever he talked, he stuttered. And whatever he looked at you, he blushed madly. Like some lovestruck fool.
