It's not 10 times slower, it's 10 times faster. If it were ten times slower he'd still be a brat, because less time would have passed for him. Seriously, he only would have aged by like one and half years. Also, previously he was six, so why was he now eight?
I know what the author was thinking, but it's not what was said. Quote, "I lived with angels and in their world time moves 10 times slower". That sentence is saying the angel's world is the one moving slower, not the human world. What it should have said, "I lived with angels, and in their world time moves 10 times faster. While I was up there, 15 years passed in the mortal world. Which means I lived 10 times that."
So, if I were to guess what's going on in this yaoi, the "gym" is actually a training facility for male prostitutes. The black collared ones are general sale, but the red collared ones are private property. It's safe to say our protag is gonna be a red collar in the future.
Honestly, what's really cool here is the "gym" can really fly under the radar. All members are "willing" as they seem to have been rewired to see sex as ordinary exercise. They still continue their normal lives, so no one just suspiciously disappears. If there's a such thing as retirement, they can reset their minds and direct them to an actual gym. Of course, the affects on the body will remain, but that's for the individual to figure out.
Seriously, all bad things are traced to him. Leaving his son on Earth, not ever interfering or even visiting. Only getting involved after the mom dies, but before the son can finish his revenge, which results in the son seeking revenge later and being punished for it. Son becomes a playboy because he can't find his mom, which his dad definitely prevented. He only falls in love with a human because he was sent to Earth by terrible dad, and for what? Cause he almost got intimate with some princess? It's not like you ever put your foot down on his degenerate ways before, so isn't this also your fault daddy-oh? Inserting himself unnecessarily into his son's relationship, to the point of trying to force a marriage. Let's say he had succeded on that. Did he think it would have good results? Wouldn't it have just been a terrible marriage for both parties? It's not like Shinhu was gonna be loyal and treat her nice, he doesn't love her, and she even got in the way of his actual love. What is this father thinking? Really up there on my awful dad tier list.
Also, I wish we could have gotten some answer on what happened to Shinhu's mom.
If I were to have listened to the comments, I would have skipped this. I'm glad I didn't since I'm enjoying it. Honestly, like night and day, the comments don't match what I'm reading at all... it IS probably like a soap opera though. Probably the only somewhat accurate comment I saw... not that I would know. I don't watch soap operas.
The ML is a huge red flag. I thoroughly enjoyed his twisted nature (though him being sweet at the end was also great). Favorite line is when he says, "I wanna pierce your neck, too." I already thought this guy looked like a vampire, lol. In another reality, this is a vampire yaoi. I'd so eat that up. A vampire BL with this sort of setting.











I like it, but I question the point of the death and second chance plot point. Seems utterly unnecessary to the story. That death isn't used to change things, because things change on their own without MC intervention. There's apparently no reason for these changes either; ML doesn't remember that other life like MC. It's also unsatisfying that MC never tells ML what happened, nor does ML ever remember on his own. Just all seems kind of pointless.
