If you and your boyfriend are walking with another girl on a very cold winter night, usually your boyfriend will take the initiative to give you his coat to keep you warm.
But at this time, the girl took the initiative to say that she was cold, and your boyfriend gave her his coat. What is your mentality?
When your boyfriend's thoughts gradually revolve around that girl, you finally can't help but bring it up, but he says lightly, "She's just my sister, you should be nice to her."
Love is always a matter between two people, and it is always a problem.
