The genre tag should include mystery and suspense too.

You are welcome:)

I think it's just inspired.

You are welcome. I think another reason could be that they are not related and Yi Ting just feel sorry for her or gulity.

You are welcome:)

I love it too, been long since I got addicted to a drama. I have watched to episode 4 and it just keeps getting better. I just hope it has a happy ending because I hate sad endings but because it's not entirely based on faust and is just a bit similar I have hope it will have happy ending.

it's in chinese and I could only understand in pinyin by google translate but here it is in chinese because I'm not good at translating:
為了復仇，不惜佈下與「她」相愛的局？

雷芯語，地產女王林蔓的獨生女，卻在回國這天，成了落難千金。如城堡般的家被查封，迎接芯語的是一群受欺騙的投資人，數落著自己媽媽的惡行惡狀，宣告破產的媽媽不知去向，頓時間，整個世界對芯語充滿敵意。
趙以霆，就是在芯語陷入絕望的時候，第一個伸出援手的人。
趙以霆，曾經是個樂天知命的普通學生，但在「那件事」後，完全變了個人，過去單純的趙以霆彷彿死了，他選擇將靈魂毫不保留地拋售，如果世界只聽有權力的人說話，那麼他就來當有權力的人，讓「那件事」的始作俑者負起該負的責任。
他與她，因為同一個悲傷故事，狹路相逢…當以霆發現，了結「那件事」的關鍵就在芯語身上，看著落魄的芯語，以霆毫不猶豫地伸出了他的手。
芯語不明白哪來的巧合，自己數度被以霆所解救。以霆是芯語的貴人，但同時也是芯語見過最冷漠的人。他帶著奇異的神情望著她，給她奇特的安全感，有時卻又像在暗處虎視眈眈的狩獵者，圍繞在芯語身旁，漸漸的，以霆佔據了芯語整個心思……
芯語不知道的是，自己和以霆人生出現轉折的「那件事」，竟脫不了關係…
更沒料到，以霆為了復仇，竟不惜佈下一場與她相愛的局？！

They could be cousins maybe or they are brothers but don't have same father because they don't have the same surname.

Lei Xin Yu is finally thinking that her mother might be not be a good person. Zhao Yi Ting is really confused though he is using Lei Xin Yu to find Lin Man and threatening Jian Xiao Ye to spy on Xin Yu, yet he is beginning to feel something for Lei Xin Yu.

the synopis from TTV/Settv is totally different which is the broadcaster's official site. there is nothing about immortality mentioned or anything supernatural. About the robot...I think it just represent his loneliness.

yeah it could be. I wouldn't be suprised if she was.

She didn't even text her instead it was her friend from America who asked if she was alright. But I'm suspicious of Qian Ni's father too.

I think she is bad, cause in the flashbacks she looks fake nice. Like she is putting on a show to convince her daughter that she is hardworking and kind. And who leaves her daughter alone like that? Why didn't she take her with her? I think something is fishy about her.

I want Zhao Yi Ting to suffer alot when he falls in love with Lei Xin Yu and I think he will and also think that Lei Xin Yu will hate him when she finds out that what he did to her. But I hope that in the end they end up together.

There is a new preview for episode 4 and he is worried about her and he is confused about why he is worried about her and even talk with the robot about it. I think he wil change.

The new preview for episode 4.

Zhao Yi Ting realizes that he is worried for Lei Xin Yu and he asks himself "what is wrong with me today" and "so...I'am worried about her" or something like that. He even smiles at her gently when she sleeps. Seems like he is slowly changing.

I think it's wrong too. The synopsis from the drama's official site is totally different. There is nothing about immortality mentioned. I think the story is not really based on faust but only has the same name as the title (faust) and maybe some idea from the faust story.

I don't think that they will adapt the drama exactly as the faust story since for now there isn't any supernatural elements and it's a drama about revenge.They could change some things. The main guy is cruel indeed but it looks like he will change because he gives that impression when he is around the main female character.
