The Grandpa's flashbacks of his memories with Misaki's grandfather made me somehow really emotional.
Reminiscing about their past, facing regrets, and acceptance. This is why I oath to be straigforward and always true to my feelings, I don't want to regret anything.
As for Misaki and Haruhito, they're nice. I wish there's more of them, it probably can't end with them just sharing a kiss.
