It's not like other yaoi which looks cliche* or straight-way plot* (yk, something that called 'normal' plot lead 1 route) psychological indeed. For me, it's disturbing, i know it but I'm not underestimating something here, i just don't feel ok continuing reading this. If you're into smth like deep trauma about life, ppl, and partners, so on and mc receiving treatment to forget trauma by sxx(???) it's complicated for me... welp, give it a try. I dropped it at 27
