It's too late. He didn't trust her the first day, he hurt her a lot and today she doesn't feel it in her heart to forgive him. He tried some chapters ago, she refused to acknowledge him as her father the same way he didn't want to acknowledge her, and now, even if he does communicate, she wouldn't trust him. Trust doesn't comeback with communication
Trust can come back with proper communication and dedication... with time of course
No, it doesn't. The person just chooses to ignore that uncomfortable feeling. That's why at the first fight, people bring up past mistakes, because they don't forgive especially if it's something that hurt them deeply.
Trust isn’t something that appears immediately after meeting someone. Who trusts somebody they met for the first time? Especially the daughter of your lover who stabbed you in the back? The literal only way to build trust is through communication, that’s… common sense I fear. Exactly how she didn’t trust him blindly, he did the same to her.
Arrrgh just communicate damn it ヽ(`Д´)ﾉ
