Story: The story is super cute and scripted very well. This is the first BL i have seen where the girlfriends are treated well... for the most part. Gu Hai also shows how much he cares for Luo Yin  he will do anything to keep him by his side. Also THE TITLE IS SO CUTE! The title of this series is sort of a ship name. Hai Luo Yin which is Chinese for Heroin an addictive drug. There are many arguments and challenges faced throughout the series that show great character development. They also reference each other and what they are going through using similar situations. This helps them realize that they are not the only person going through the same situation and that the way they are acting is truly unnecessary.  The only thing i can argue with is a lack of explanation during some scenes. I did my best to make sure i didn't miss out on any deleted scenes so i don't think i missed anything. There are just some scenes where we have a conflict and its not exactly settled it just goes to the next scene. The next scene usually makes up for it big time. So much that you almost forget what you felt you missed out on. But i would still like a little more information on certain things that happen.

Acting/Cast: The acting was amazing there is nothing to really complain about here. All the actors did their parts and acted them out super well. They each portrayed their character the way it was intended. I really felt the relationship between Gu Hai and Luo Yin. The way Gu Hai felt when Luo Yin acted a certain way. The times they were there for each other. It really made me feel that they were actually in love. Not just in the series but even outside.I do have to say that i could hear the machine that makes the rain during one of the scenes but not many people would have noticed that. In fact most people probably thought the rain was real. To me that's kind of a big deal but nothing i could take points off for.

Music: The music was to die for. The opening song makes me teary eyed. Not to mention the upbeat music played throughout the series. I might be biased to this but i really love a good violin or piano so when they played those the scenes just became 10 times better. Not to mention the cute songs sung by Bai Luo Yin (well not sung by him just that he sang them during the series) and how they used that song to create an emotional connection between the two main characters.

Re-watch Value: If you are ok with the fact that there is no season 2 then i would definitely recommend watching this again. I try not to because it makes me sad that they left it off where it was expecting to continue with a season 2 but it got shut down by the Chinese government. which is the reason i gave it a lower re-watch value. If you do decide to watch it i recommend watching it around December or late November because you can really feel the cold and the season as the episodes progress. Also if you can watch it with someone else. Maybe even someone special. If you don't plan on stealing the cute lines from this series and using them on your significant other.

TLDR: very good series. Music is cute. Acting is amazing. Re-watch if you like happiness followed by depression due to a shut down season 2.
