You are a very attentive sister, you care about your brother so much, he must feel very happy, but at this time, the boy will definitely have his own girl who likes you, at this time he will be a little confused, maybe he is not confident, as a sister can just educate him.
You can give him some advice from a girl's perspective, and encourage him to make him confident, boys are the most handsome only when they are confident, right?
Haha, girls should like sincerity and gifts, let him tell the girl what he thinks in his heart, and it would be great to give him a small gift by the way, you can help him choose a small gift.
The younger brother is in a bad mood, and things are not going well. He needs psychological guidance, and giving gifts cannot completely make him recover.
