It all starts in the usual desperation: "I am not gay and yet I love this man. Also, he just got married." From here, the story twitches amongst the groom, this unfortunate best man and one of the bride's friends.
What makes everything fun is that the situation is actually possible. The characters are also very real. Their trouble is actual and the ways they use to solve it are also expected from real humans. This is what turned an average male-on-male romance in an entertaining piece. The light humour and the pace of the speech also contribute to this.
The great annoyance of "Close the Last Door" is the diminute and almost forced love scenery, that doesn't seem to fit in the whole light-hearted mood. They are stuffed in the middle of other scenes and don't even show what I would have liked to see (and most fangirls, for what matters)
Still, it brings out some good laughs.
