I feel for Rael both in her toxic relationship and how badly she wants to be Yunifer's friend, but you can't force her to be your friend. If she is clearly stating she doesn't want to eat lunch with you then you stop trying. If she is continuously uncomfortable around you then you stop. Rael seems like a sweet girl so hopefully she would be able to friends with the other docs. This comic is going to get annoying real quick if Rael doesn't start backing off.
