Since you two started to date he felt the luckiest he ever had; having a boyfriend like you was his dream come true and he loved you more than anything, of course he wasn't afraid of show it that to you, alwaysa clinging on you and being as close as possible

But there was something on the back of his head, Denki knew that probably you deserved someone better. After all, he wasn't the smartest guy around, nor the most handsome and even less the most muscular

Slowly those thoughts got the best of him, making him feel like he didn't deserve you and that you needed someone better, so with his heart breaking slowly he sneaked into your room and clung onto you with tears on his eyes, mumbling

"I'm sorry...I'm not...I'm not who you...Deserve"
