The only manga I could think of would be "Ten: Tenhou-doori no Kaidanji". It wasn't anything special but I remember it was 2016 and I was in my 2nd year of uni and at home during the Christmas break and spent most of that time having a mix of reading Ten, eating a Mr Kipling's Frosty Fancies (which I now get every Christmas period) and playing random games of Overwatch with my friend who was into it a lot at the time (I kinda was I guess as well). So whenever Christmas rolls around it's surprisingly one of the memories I remember the most. My friend has recently go back into OW and I'm probably going to eat some of those Frosty Fancies again while playing it with him.
The manga requires knowledge of Mahjong to fully appreciate, so if that's too difficult the only other manga I could recommend would be "Rookies". Mainly because I read it around Christmas time of 2018 and absolutely fell in love with it super early on and basically read it all in around 5 days, it's truly a fantastic manga and my favourite of all time.
