I know that heavy sponsorship exists in k-dramas (I'm sure that any kind of drama/soap opera/telenovela counts... but especially k-dramas), but... I think this is the first time where I see this phenomenon in a webcomic/webtoon???? What's up with that? xD
What a... weird way for an ad for oatmeals. In a webcomic (although, ngl, I am always up for a plate of oatmeal as I can for breakfast, lmao, I got hungry the first time I saw this at Naver).
