Glad it is not a full fledged manga because the story revolves around a singular theme, which could have possibly gone stale if it was stretched for long. But I guess we wouldn't know. A girl tries to get close to his crush but he wants to die. So she sort of tries to make his day a bit eventful. It gravitates more towards the comedic side. The type of comedy which only packs a punch when used for the first time but becomes flaccid the moment it is used for the nth time. And the author too seemed to know this. That's why it isa one shot.

Nonetheless a decently fine one shot, not good not bad. You should read it, I mean its a one shot and will take 10 minutes at most to complete so go for it I guess.
