Yeah I found it so sad but endearing 😭 (despite the tragic circumstances). They may not be biologically related but they both have this same reserved personality. It was heartwarming to see them awkwardly bond and for him to gradually come to understand his grandmother better; that he was cared for and not just out of obligation but love. The fact that he didn't see that his grandmother cared for him at the beginning made it all the more sad but realistic for me. 😭
