My recommendation: The famous "Ji Dao Xian Shi" *** three, personally think the second one is the best; "Symphonic Lover's Dream", I watched Chong Juri, it is good; "Absolute Heshi", Hayami's favorite one; "Secretly Falling in Love with You", the Japanese original version, adapted from the manga; "Ace Male Publicist", a very realistic drama; "Wild Boar Makeover", Kame Rei, Yamashita , Horikita Maki. Of course there are many classics...
Answer 2: Ah... "Last Friend", it happened to be on the air when I was in Japan and I have been following it. I mainly watch Juri and Eita, but as far as the plot is concerned, many people can't accept it. It depends on personal acceptance. Each character in the play suffers from a psychological problem or disorder, which is very professional and reflects the problems existing in society. It'll be nice to watch the later part, it won't drag on, the first episode just explains the relationship between the characters.
