He's actually dancing on top of poor squashed Usagi.
Mamoru is VERY mad right here.
Mamoru almost NEVER makes funny faces...well, here's one for you!
Tuxedo Kamen is always serious, while Sailor Moon is not.
This is from the episode in which Ami decides that she likes Tuxedo Kamen for two minutes, but then says she has to go and study.
In the beginning of the series, Usagi and Mamoru couldn't stand each other, and Usagi envisioned Motoki, her crush who works at the arcade, as Tuxedo Kamen.
The entire plot of the Doom Tree series: Usagi is in love with Mamoru (who lost his memory). Ann is in love with Mamoru, but dating Ail. Ail is in love with Usagi, but is dating Ann. Mamoru is in love with nobody, and wants them all to leave him alone.
Rei was in love with Mamoru before he and Usagi fell for each other. Rei called Mamoru twenty times every day, made plans for dates, and just wouldn't leave the poor guy alone.
Tuxedo Mask has a beautiful locket that Princess Serenity gave him long
ago, and when he accidentally drops it near Sailor Moon, she begins to
remember a little bit of what happened in the Moon Kingdom. When Naru
sees Usagi looking at it, she says, "Oh Usagi, that locket's gorgeous! Was it a gift?" and Usagi replies softly, "Yes...long ago."
Usagi remembers her Tuxedo Kamen sadly, because she thinks he is no longer on the side of the senshi because he kept a crystal.
