Would you let your 13 year old daughter be friends with a 15 year old boy?

My 13 year old daughter has recently made friends with a 15 year old boy and I'm not sure if I should let it continue. She's a very careful girl and has assured me that she doesn't trust him yet, and they only chat on Instagram and see each other twice a week at a supervised drama group. I'm not sure what to do.
