If you fall in love with the sister of your best female classmate, it's not a very embarrassing thing. You can tell your classmates generously, don't hide anything, women are not as narrow-minded as you think. Maybe she'll be happy for you when she knows about you two. Since you have a good relationship with your classmates, your classmates know all aspects of your personality. Your relationship with her sister may not be as bad as you think.
Just like when I was not in love, my sister always tried to make do with me and the boys who had a good relationship with her. Because what she introduced to me was what she thought was good, she thought that the rich water would not flow out of the field. Of course, we should consider our own people first.
There are also many people around me who are in love, whether they are classmates' sisters or classmates' sisters. Many people will introduce their friends and girlfriends to their sisters, just like my brother once said that I really can't get married, so I will forget it with one of his good friends. So you hooked up with your best classmate's sister. It's not as bad as you think.
Besides, it is not unilateral for two people to fall in love, it is two of a kind's choice. As long as you tell your classmates truthfully and let her know through other channels, you won't be unhappy.
In addition, if you think your best female classmate has a secret crush on you or likes you, and you feel embarrassed to secretly love her sister, you should tell her the truth. On the one hand, let her give up on you, on the other hand, it is also a respect for her and her sister. You secretly intimate with her sister in private, because you are afraid of hurting her, so you hurt her and her sister.
Just like Tang Ming in the TV series "Crossing the Ocean to See You", she obviously likes Yan Xiaoqiu, but she always welcomes Chen Shanshan's confession on the grounds that she doesn't want to hurt her. In the end, she can only spend the rest of her life in regret and sadness.
Furthermore, if you have pure friendship with your best female classmate, since you are in love with your best female classmate's sister, you should be kind to others and be responsible for her. You should also tell your classmates your sincerity and let her rest assured, because after all, it is her sister, and she still wants her sister to be happy and not to be hurt.
Therefore, in this era, if you can get rid of single dog and meet true love, you should cherish it and don't miss it. As for your female classmate, there is nothing to be embarrassed about.
