Seven Days is a fairly happy shounen-ai manga. (There are some heavy moments of doubt, I think, but it's not like someone's going to die, or that they're going to break up. Well, in their perspectives...) But it's cute overall. Like really cute. And sappy. And like, about half way through, it's like, "Just kiss and get together!" /wants to add more, but spoiler~

XD Then I guess I can somewhat recommend Bukiyou na Silent because there's no real drama. (But then again, I thought the main character was adorable when they started crying, so...) But the main character is cute. Even when stoic/deadpan.

And Eiji, why you look so "Ugh" when you were just nearly crying over him? Or was he crying? I forgot already.
