From Tappytoon:
Yu Nian feels his dreams have come true when he gets to walk the red carpet next to his biggest idol, Xie Youjun. This has him immediately thrown into the scandal of the century, but the drama doesn’t end there. When the event they are attending turns out to be on the night of a full moon, Nian discovers Youjun is actually a werewolf and consequently gets bitten by him. Although a typical human should have died after such an attack, Nian is perfectly fine the next morning, albeit with a mysterious new mark on his back. Unbeknownst to him, Nian is an omega who has the ability to tame the beastly nature of the alpha Youjun…
