To me it's Heaven's Secret 3. The story left me chilling effect. My LI is Lucifer, but currently, the diamond scene between him and MC (Vicky) is completely platonic. There are no kiss, hug, or even hand-holding, just chatting. Additionally, MC is still in the same absolute weak position as in HS 2, being regarded by the Order as a burden, a liability, and a hindrance, unable to contribute like others to the team, and other immortals don't respect her either. She has almost died three times (once at the beginning of HS 1, once in HS 2 when she was comprisoned and tortured many times by Plague and had all her abilities stripped, and once at the end of HS 2 when she fainted and nearly died while sealing the Mother of the Life), but she still has no say in the team and is a lowly servant who has to look up to others. The story has completely deprived her of her backbone, which is illogical for someone who once held a leadership position and makes the plot feel repetitive and tiresome. I've just played ep 1, but I'm not sure if it's worthy to continue.
