Christmas has a more private, one-on-one connotation. A kind of optional extra. So the "will we spend Christmas together?" question comes up more than once with couples.
In Yamada's No One Loves Me, reserved Katushiro takes a leap in his relationship with Masafumi when he brings Christmas chicken.In Fake, Dee shows up to Ryo's apartment with his teeny tiny tree!
In The Metalhead Next Door, baker Soshi invites Kento to share a yule log with him.
In 10 Things I Want to Do Before I Turn 40, the male protagonists have an actual lovely run-to-each-other moment (but not in an airport!) when they decide to spend December 24th together.
Romance is all about fragile hope--appropriate for the season, which is so often associated with a single birth, a winter solstice, a candle in the window, a space of warmth in snowfall.
