You're insecure

This 'issue' was with you since your..childhood. Those kids had bullied you for no reason. So what? You're chubby. So? You're beautiful. Chubby AND beautiful. Just because you're not the skinniest doesn't mean you're ugly.

However, they didn't want accept that. Especially you're a chubby boy..they aren't able to accept it. Why? It's normal.

It didn't even limit you, you're good at physical activities, right? You're healthy.

Sometimes your insecurities went too far and those bad thoughts came..but you've found a boyfriend. Someone who loves you for what you are, he loves your body too.

Now..he had noticed you're feeling down.

"Love, What's wrong? What's with that sad face?" Izuku asked you and sat next to you.

"Do you want to cuddle, perhaps?" Izuku gave you a smile as he wrapped one arm around your waist..squeezing you lovingly.
