Sharing Our Innermost Thoughts

Not much of a thought, just a question. There is this guy who got more beautiful/handsome over the lockdown, and Sometimes he is being nice to me by askin for things, and sometimes just ignore me. I am cute but a lil chubby (Bigger bod person as compared to petite girls) how can I ask him out?

Also, he’s always been this conservative shy guy, who just stays in his group and doesnt talk with much girls.
