gu wei yi and si tu mo are so cute together. They go through lovely as well as funny moments. I really liked the drama till the end. I don't think I am very happy with the ending where they have a kid. I think that the drama should've ended with them just getting married. The other characters are interesting too . I really want to mention Gu wei Yi's jealous lab mate. He is so funny. Even his teacher was funny. I wouldn't watch the drama again, but I think its pretty nice for a one time watch.
