Lu Jin is sure of his feelings. He is mature, decisive and loves Shegnan to the point of being possessive and fighting for her and protecting her all the way. Now, that is a man!
I think one of the differences between the men is how they deal with rivals. Ziqian, instead of going to Shengnan and telling her he likes her, he goes to Lu Jin to try to convince him to break up with Shengnan. Lu Jin, as we see later when his brother comes into the picture, doesn't go behind her back like that. Any issues he has, Lu Jin goes straight to Shengnan and tries to fix the problems with her. It's one of the reasons he's the "better" man; he's very straightforward with his approach.
This man truly exerts confidence and presence that demands attention. Even when other guys are taller, you never even notice the high difference. All you see is how big his presence is 👏🏼
I get frustrated sometimes with these shows where one person says something like “ can you look after her all the time, be with her every day” etc etc etc. I know caring fir your partner is important in a relationship, but sometimes I just want to yell at the screen “ SHE’S NOT A CHILD! SHE DOESNT NEED A PARENT!!!!” 😤🙄🤷🏻♀️
Her childhood friend would have been a great guy for Gu. But she fell for lujin . you can't help who you fall for. He was ready. To take of her. Her family. !
