I don't ever care anyone say Seo isn't romantic enough or what but i'm respecting his daily routine. Cleaning his home, gathering with his parents. Ah, no wonder Kotoko fell in love with him. He's family-oriented guy. <br /><br />Even in the Kei's case, Seo still can be matured and supporting her hobbies with simple and organic way. Yes, this is almost look like mature relationship. <br /><br />I hope the author give us multiple ending like Bokuben and called it canon happy ending for both of them
