Tbf, he did not expect to be forgiven right away. He also did his part to reassure her. Even closed his eyes when she snooped his phone. Adjusted what needs to be adjusted. But let's be real, they are partners. It takes two to tango. So she may as well do her part. If they both agreed (non-verbally) to go with the status quo, then she should try to keep it as well. Otherwise, offer to talk it out. She already resorted to physically hurting him. But she as per usual brushed it off.
Sure, he could have initiated to talk but he's not the one resorting to attempted murder.
Recalling their relationship before and after the incident, I'd say it's still the guy giving 70-80% effort into the relationship. Maybe 85 to 90% after the incident. Hence, it's still unbalanced. I'm not hating her, I understand her, but it has come to a point where she needs to address her behavior instead of justifying she was a victim or she's still hurting.
The people who hate haeru don’t understand how cheating destroys any and all trust you had in your partner, especially for someone like her who doesn’t have family or friends to rely on (which is an issue in itself, but you can’t expect her to just move on from this simply because he said sorry)
