What's a smut/yaoi manwha you read but you didn't expect it to be one because of the art style??

I remember reading this one yaoi with this scientist that makes like sex toys and a spy working as his assistant gets information on his toys. Idk sonethhf about the art style just seemed so soft to me and I didn't look at the cover fully so I completely missed the sex toys surrounding them LMAOO. I was so fucking shocked when I saw a dick pop out
