Personally, I like Gu Dan who has a little more emotional lines. I don't like being sullen, being a heartthrob, and being mentally retarded and Machiavellian. I give it four stars because the system doesn't allow me to give it five stars.
The story is well written, and the sourness of secret love is expressed in such a way that people can relate to it. It's a good article. I regret not reading it earlier. When I found out about this book, I didn't know why. I thought it was about two people in their thirties falling in love, so I didn't click in to read it. I didn't expect that it started when I was 19. Fortunately, I didn't miss it.
