Warning Spoiler alert
I don't think this is right I think this might be the reason but I can't really tell you the details cause it might spoil the other readers but it's something about their past
the seme experience something bad that the uke did now his doing the same thing the uke did to him in the past
And i think the title reverse thinking is not the original name but the part reverse is actually there I just think that the "thinking" part is not the right nam
( Please keep in mind I just think this is the reason and about the title being wrong I just think ok no hard feelings
Almost read that lol
Why was it called reverse thinking tho? I'd it like supposed to be reverse psychology? Like if uke plays reverse psychology on seme, then that's how he beats the seme. Seme srems to like wordplays anyway,
