First of all, you have to find a way to get to know him, know what kind of girls he likes, and then work hard in that direction. Remember, it is ok to change yourself appropriately, but don't be too indulgent and wronged. Falling in love is a matter for two people, and we can't just consider his enjoyment.

In terms of appearance, if you feel that your body is not up to standard, exercise and diet control are essential. In addition, get a haircut that suits you (I don't use the word "hairstyle" here to avoid misleading), improve the taste of clothes (you don't have to buy expensive clothes, some clothes look elegant although they are cheap), and you can learn makeup when you have time, which can add a lot of color to your appearance.

Internally, I still suggest that you be yourself. Don't change your nature to cater to a person, but you can show his favorite personality appropriately. This requires getting to know him first. However, it is always right to read more books or take part in some elegant activities. Cultivate one's self-cultivation and benefit for life.

Since you can have frequent contact with him in the future, you should brush your sense of existence properly, don't brush too much to avoid causing disgust, and don't brush yourself as a woman or just a friend. The temperature is up to you, remember to pay attention to his mood at any time, understand his needs and preferences, and adjust your rhythm appropriately.

Finally, I wish you a happy ending with the male god ~ Come on!
