I like a junior, but I am very upset. I am a doctoral student, and I like my sister with a master's degree.

You are not young, after all, one is studying for a doctorate and the other is studying for a master's degree. If the relationship between your wants to blossom and bear fruit, it can't just fall in love for the sake of love, like ordinary college students. After graduation, your life will change very quickly and greatly. Can you understand what I mean?

You look at the conditions of yourself and your partner, and decide whether you are destined to get married from the material and future employment direction. If it's impossible, it's better to keep family friendship than to lose it later. If possible, take the initiative to ask a girl out. Eat, go shopping, watch movies and enjoy the night view. After all, it is better for men to take the initiative. It would be great if she wanted to.
