Why did Kim suddenly like the teacher elder sister?

Because of Jiang's unique charm, he deeply touched Jin.

Like a person, starting from the face value, respecting talent, conforming to personality, lasting longer than kindness, and finally being personality. In terms of face value and talent, Jiang is not outstanding, but she is very congenial to Jin and has a good personality.

At first, Jin thought that Jiang's dislike was really as plain as everyone commented, and he didn't like it. Having been in contact with Jiang for a long time, Jin began to find that Jiang's tired body has many bright spots and is a very good girl.

Secondly, Jiang's dislike of the Kim family is not to cling to the Kim family, but to really like him. Kim was born in a noble family and met many girls, most of whom came from his family background.

For those who want to cling to him, Kim hates him from the bottom of his bones, and Jiang is tired of leaving him, not because of Kim, but because of his people. Otherwise, Jiang will not decisively refuse to leave when he is interested in reunion.

Moreover, Jiang's deep boredom with leaving made him slowly fall in love with her. Although Kim has made herself feel sorry for herself many times, although her younger brothers have no good feelings for Kim, Jiang Lei is a very persistent person. Since you fall in love, you won't regret it.

Therefore, out of concern for Kim, she gave her own soup to Kim. Although Jin misunderstood him, after the misunderstanding was lifted, Jin really realized Jiang's dislike.
