Plus if her being a stranger to him was reason for him to act like that then him being a stranger to our Su Luxia was reason enough for her to act like that towards him.
Yeap. Su Luxia being a great queen that she is, leaves him alive but with the torment that probably gonna haunt him. This is "Karma", he does this to someone, others will do this to him as well, she loves him and dies for him but he didn't care, drove her to suicide. Now, he loves her and she didn't care, he will never have her.
Is all about Karma, and i love it ヾ(☆▽☆)
To make things clear, I don't want to make people feel that they should have to take responsibility when someone has a crush on you and accidentally does something stupid. It is good to make it clear that you're not interested in that person, or not in a relationship, and few times ignore them is probably a good choice.
The only point I'm trying to prove is, when she's clearly on verge of death, being bullied and isolated, about to jump off the building, he could have done something to prevent it.
It's kinda yikes at some people start to pity the male lead and start to point finger at the girl who already dead ┑(￣Д ￣)┍
While they have point, mind if I remind you that even if she choose to suicide over love, it's not something you can blame her, she is in her teenage, being dumb and act recklessly is a part of being a teenage, not to mention she also gets heartbroken AND being bully, blackmailed, of course, it will scare the shit out of everyone, and she's also isolated from school, being alone when everyone just makes fun of her, calls out her parents name.
Male lead doesn't do anything, he just being cold-hearted to her, from the start she just a stranger to him, is not his problem to take care of her? Fair enough, but I also remind you that this girl has a family, she's the only child in this family, her parents have to work hard to earn money for her studying. Now imagines they have news about their children die from suicide with bruises and ripped clothes.
Do you think they can get justice from that rich female lead and the male lead? Hah, they will use the money to silent everyone. She's not his responsibility, but when it comes to the matter of life and death, it doesn't matter, because he could have prevent it, save a life, he could have said look I'll help you, don't do anything rash, but instead he said he doesn't give a shit and even drove her more into her suicide path. This is what people meant when they said "Karma". He's being irresponsible, and Luxia not killing him, but making him regret his choice for killing someone with this cold-hearted ass.
And I think this is the best ending.
