Well if u can't do any of those and u don't have the courage..
Try to be a positive and supportive person to him

I don't have any money, and it almost doesn't fit me. Rarely suitable but... I'M SCARED

I can give ya tips!
1-Give him a compliment (Jokingly so he doesn't suspect u like him)
2-Make eye contact when talking to him
3-Smile when talking to him
4-Maybe buy a small gift for him? [Candy, chocolate, Food, Something that is small and can be putten in a pocket]

Great drawing 👌

Cool name
