You and Denki have been best friends ever since the first day of U.A. You two are so close that people often think you two are dating. It's obvious he has a crush on you, since he tries to act tough when your around. He even tried to stand up to Bakugou once (He got pummeled after).
One afternoon, the both of you were in your dorm, hanging out after a long day of internships. You were telling Denki about a patrol you were on while Denki listened, having the most comedic starstruck expression on his face. He let you speak, watching your expression and body language every second he could.
Denki then spoke under his breath. "Will you marry me?" He didn't even realized what he said until he heard you stop speaking and look at him with a surprised face. He then started stammering, "S-Shit- Balls-" He was shocked at himself, and slightly panicked at what you'd say next.
