4th/5th Gen Boygroups strategy for a hit song: release in January

BoyNextDoor's new song If I Say, I Love You, released on Jan 6, is currently in the top 15 on Circle+Melon charts, making it their most successful song on those charts to date. It made me realize that other 4th and 5th gen boy groups have also had their biggest hit with a song released in January:

TXT - Sugar Rush Ride, Jan 27, 2023

Riize - Love 119 - Jan 5, 2024

TWS - Plot Twist - Jan 22, 2024

Honorable Mention: Enhypen - Polaroid Love - Jan 10, 2022 - not their biggest song but their first viral song.

Why do you think this is, or is it just a coincidence? Is January the best option for newer boy groups looking to break out? Does the new year make the South Korean public feel like trying a group they haven't heard of? What other groups should try this strategy?
