I didn't particularly like this but only because the story was way over the top, the believability factor was just too low.
But I can guess why people might have liked it - forbidden love, two very pained, traumatized individuals finding each other and being healed by each other. I assume you read the whole thing, in the end we find out that seme assaulted and blackmailed the uke because he thought it was disgusting since he himself was assaulted and blackmailed by his stepfather, whom he killed (his backstory makes sense why he is a bit unhinged). But uke rejected his brother and that made seme see that he was different from his stepfather. Uke is realistic, he knows that loving his brother would ruin the very future he wanted to protect so he acted like an adult and stepped away. While I don't understand forbidden love like this - i do imagine there are people who have experienced it and it was beyond their choice to fall in love. But they do have a choice to act on it, which is where the uke redeemed himself in the seme's eyes - he didn't act even when his younger brother expressed his own feelings for uke.
Personally, I thought the scenes were ridiculous - like those three guys also deciding to blackmail their professor so they could have sex with him (all in like 1.5 chapters) lol just too much.
To anyone who actually liked this...please can u tell me why...
It made like no sense to me...even for BL the rape is normal and it's normal that the bastsrds who hurt the uke are set free but like the whole story was so....meh....
