Netflix Korea sparked buzz on March 18, 2026, with a new Instagram post promoting streaming for 'Monthly Boyfriend' and urging fans to screenshot and use fresh personal wallpapers.
The images capture the two leads in cute, lovable poses, paired with the message, "Here it is. My wallpaper this spring. Screenshot and use it," nudging fans to set it as their background. Playful icons added to the visual fun.
Fans quickly reacted. Comments like "Ah~ so pretty" and "So cute together! Season 2 please" poured in, with growing calls for a second season.
