Miguel Mora!

He was your best friend since you were kids and you invited him to your house to watch a movie, you were alone since your mother had gone to pick up your little sister at a friend's house

When they arrived they saw you and Miguel hugging each other watching the movie, your mother didn't say anything she just saw them with a smile and the little girl who was five years old told them

"They look like a couple"

After that he went to his room and you blushed at what your little sister had said
