Everything's about the drama is on point, the script, the acting, the actors, ost, etc.. The drama's pace is comfortable for me to watch, and I can relate to many things that happen around the families, especially Lin Tou's. Nevertheless, it's just a simple sad story that would take my tears (lots of tears) so I would give the rewatch-value a not very high rate.
The only thing in the drama that makes me annoyed is He Xin Di's personality and her ugly hot-temper in some scenes. Her marriage with Chen Guang Pu is also fast and questionable to me as the drama has no time for their relationship development.
Unless, it's a good story with good plot, providing me new knowledge about APLS, which I didn't even know about before watching the drama. Finally, I have to give Lin Yi a praise as his acting is so on point despite his young age. This is such a talented actor and I feel no regrets when tuning in the drama bc of him.
