I really liked this drama, and season 2 contained a lot more action then season 1. We got to see a lot more vampire hunters as well as a completely different side to the characters that we've already met.

I loved Ya Long. He was my favourite character as well as the most open and honest character in the entire series. I loved all his moments with Ye Yin and I wish there were more, especially in the present time. I wanted them to be together so bad.

I pitied Si Yin in season 1, especially because I felt there was unrequited love on his part, towards Ye Yin. I didn't at any point ship him and Ye Yin, they had more of a family bond, no matter what reincarnated version we saw of him. I also found it a bit incestuous for either of them to have romantic feelings for each other because Si Yin litterally adopted and raised Ye Yin. After finding out more about their past life, it definitely seemed incestuous for them to be together romantically. Si Ling (Ya Long's past self) litterally said that it was not right for them to be together because (SPOILER) Yi Sha (Ye Yin in her first life) was literally made from a rib of Sha Ka (Si Yin's past life), and she was made for Sha Ka's best friends, Si Ling.

If anyone was intruding in the romantic relationship of Ye Yin, it was Si Yin because it always seemed like Ye Yin and Ya Long were meant to be together.

Music/Sound Effects:
Also, I just loved "Stately Suspense" from "The Task: High Pressure Strings & Beats". It was my favourite soundtrack in the entire series and it played whenever Ya Long and Ye Yin met in the present. I mean some of the sound effects this seasons were just weird, a mixture of Star Wars ligtsaber sound effect and old video games sound effects. But "Stately Suspense" really did it for me.

More of a SPOILER review below:

I find it ironic how when a lead character is introduced as 'evil', they usually end up being the good guy and when a lead character is litterally introduced as the 'good guy' he is more of a bad guy then the 'evil' character. This was definitely the case for this drama. A character that was constantly described as evil had more of a moral compass then the good guy.

Both Ya Long and Si Yin were in love with Ye Yen. I felt like Ye Yin genuinely and romantically loved Ya Long but couldn't truly express this love because if all the promises Si Yin made her keep. Ye Yin loved Si Yin as her "master", a family member and either an older brother or father like figure because he adopted and raised her. She kept her promises to Ye Yin because she felt that she owed him and no other reason, not even because of her familial love for him.

Towards the end of this drama I started to hate Si Yin because despite how much he claimed to love Ye Yin, he never truly loved her. He loved her past self, Yi Sha, and even that wasn't love, it was possession for the being he created. He was the villain to the story and I really hated how at the end Ye Yin sacrificed everything in order for Si Yin and Ya Long's past friendship to stay in tact and undo the entire plot of the drama. Just thinking about how tragic Ye Yin's ending was makes me really sad. Ya Long and Ye Yin deserved their happy ending. I HATE dramas that end by essentially undoing the events of the entire drama.

I gave this drama such high ratings because it wasn't bad, just the ending was. It had everything that I love in dramas: action, romance, historical, time-travel, supernaturel and VAMPIRES. Honesty, Ya Long deserves a 10/10. He reminded me of a better version (personality wise) of Gwi from Scholar Who Walks the Night and I was only able to finish that drama off because of Gwi.
