My guess is Jun is Dodosol, and that as soon as he finishes school, he will start messaging Rara again. He made a deal with his dad to protect her.

    Probably the deal went like this: you give me the money to buy the building, and I agree not to contact her (except to break up) until I have graduated from college. I wouldn’t be surprised if the family hired that rude girl to make sure he keeps his promise.

    I haven’t watched the last episode yet but that would be my guess too.
