So the MC is an attorney who is basically covering for his little brother who has a messy lifestyle despite being somewhat of a celebrity I guess. The younger brother implied he slept with that dirty old man to get further connections and job opportunities.
The MC went so far as to even masturbate on the dead old guy and make it seem like he was the one who was with him when he died.

This doesn’t even qualify as shounen-ai, it was literally all platonic. Point blank. Nada, nothing of that nature. Two male leads and their growth along with friendship doesn’t equate to shounenai. And anyone who says it does is reaching. Not even a sprinkle of romance.
Nonetheless, still a good story and read.

We’ll most likely get some closure with wren in the final chapter if he is dead. Him living on in some way, whether it’s through a physical or space sense. Either way, this whole scene is pretty surreal and magical. I like how the series is ending. Which is rare, most series lose steam towards the end with poor endings that leave me feeling empty. I don’t feel like that either AOT here even after all these years. It feels right.
it's very much an open ending. I'd like to think he did survive given he promised he would live on for him.
