True, we do witness his suffering, and it seems he needs time to reflect on his past mistakes in their previous marriage. His love for her before her death, coupled with his conflict with the government and trust issues, adds complexity to his character. While his actions aren't justified, understanding his perspective in a new, untrustworthy world, manipulated by both the government and the saint, offers insight. His yandere archetype exacerbates the situation, making it difficult for both of them. Hopefully, he'll endure more suffering and come to recognize his faults. It's unlikely our FL will easily forgive him...
She is still in love with him but it doesnt mean she wants to be with him. And the blushing make senses cuz SHE IS IN LOVE AND THIS IS THE FIRST TIME HE'S WRITING HER. I can relate with her. But she is not dumb, she already refused the proposal. Love is not something can end that easily girlsss. Even most of the broken marriages are not ending because of love.
