Christmas.

For me, Hasegawa Yuta, who became single a month ago after my girlfriend cheated on me, it's a word I'd rather not hear.

Only a few days left until that Christmas!

After parting ways with my female friend, Mino Ayaka, after our usual conversation, I encounter a beautiful girl dressed in a Santa outfit in a town overflowing with couples.

Her name is Shinohara Mayu.

Could my encounter with Shinohara end up being a Christmas present for me?

Achieved #1 in the daily genre rankings three times on Shousetsuka ni Narou!

Upon its book release, the title was changed from "I, whose girlfriend cheated on me, met a beautiful girl Santa just before Christmas"!
