No manhwa can be both shounen ai and yaoi. Bc one doesn't have smut and one does. You're just looking for yaoi that lean more on the plot side and don't have smut that spans chapters upon chapters.
That being said you can try these bc they fut your criteria:
The third ending (smut after s1)
The pizza delivery man and the gold palace (smut after s1)
Dreadful night (plot focused)
You and I can't do this (begins with smut but doesn't have much later on)
Smyrna and capri (begins with smut but doesn't have much later on)
Okay ranting real quick but I get pissed off bc sometimes I can’t find shounen ai stories with Yaoi smut …if that makes sense, like I want a story with a mix of them kissing and sometimes the occasional smut idk if that sound weird? But finding a good balance is so hard T^T bc it’s either they don’t kiss till the end of the series or all they do is fuk like most of the time there is no in between I WANT A GOOD STORY THAT HAS ME INTERESTED AND THEN TEASE ME ABOUT THEN KISSING AND THEN IT ACTUALLY HAPPENS AND THEN THEY ACTUALLY HAVE A REAL RELATIONSHIP AND ACTUALLY LOVE EACH OTHER if that makes sense lol yk?
