If you make a huge mistake that impact someone's life negatively, deal with your consequences, apologize, learn from it, and move on. The person you're saying sorry to are not obligated to accept your apologies if they don't want to.
I'm soo glad Hyunho grew some spine to leave that toxic douchebag. Man, I love this plot.
It's totally understandable to be upset after seeing such a thing but I think Hyesun's being a little too emotional. If only she had given him the benefit of the doubt and took time to sit him down to talk seriously like normal adults, I'm positive they could work something out. Also, the both of them were in a state of shock so it's impossible to think clearly.
I understand where she is coming from...
How tf do I block this shit? Actually, no, how do I get rid of its existence on the Internet??? Nobody should suffer reading this trash (╯°Д °)╯╧╧
