How can I reply when the girl says dd?

You can inadvertently ask her face to face what she means. If you really can't, forget it. After all, feelings are two people's business.

The real high EQ is to dare to act:

Because the education from childhood has never taught boys how to fall in love, many boys always follow Nuo Nuo when they meet girls they like, and dare not express their likes to them. His starting point is to make friends with girls first, and he wants to make a transition from friends to lovers, but finally he really becomes friends.

Men with real high emotional intelligence will actively express their love for women (expressing love here is not confession), show their attractive charm to women, and finally successfully attract girls they like.
