Like in many stories, the mc hesitates or takes a long time to even return the ml feeling. I want a uke who absolutely loves the yandere ml and stands by him firmly early on no matter who says what. He does not care what kind of crimes or things he do. I love mutual love and protective. The yandere ml should not be cold.

But half of it is only smut and the proportion of body in addition to tiny head is throwing me off.

this is me when i first start reading manhwa lmao. there's good ones out there, you just need to dig deeper (storyline with actual plot + balance smut + bonus if they have a nice art style) but some with “yaoi” tag tends to have toxic characters with little to none redemption arc or just bad writing in general.
i suggest you start with shounen-ai manhwa instead of manhwa that have smut/yaoi tag, that way you can also avoid being jump scare by uncensored humongous dicks, and get used to it (i did not, in fact, get used to it)
but yeah, its manga >> manhwa for me.
Like the uke is the one overprotective like seme, grab chin and manhandles seme, is genuinely scary to anything that is a threat to seme. while the seme is soft.
