the MC is a dog?? Many times he's lustful for ML in dog form, well he did turn into human after that, but the MC sometimes still act like a dog to please the MC

many times the ML wish the MC to be a dog back, because he like the furry feeling

and in the extra, the ML approved MC request of getting intimate in a dog form

that's looks like a kink to me

they were both horrible. ML's non-blood related father maybe just a notch lower. He gradually fades out into the background as he remarries and cares less about ML. His parents were just horrible though. I kind of wished to know his reaction to seeing ML being successful later on but it was probably good that his character faded out for good after ML became totally dependent. And I liked how cleanly ML cut him off as he knows it wasn't good to depend on that father. The ultimate s*um is the mother who comes back near the end of the book and luckily was easily dealt with. Good riddance.

I found the whole going blind thing very frustrating. Like how at the beginning he had terrible night blindness, crashing while biking etc. MC was terribly concerned even before his family situation got worse but ML just didn't seem to notice. Like why didn't he notice all those signs sooner? Cos poor vision and not seeing at all at night are like big red flags. Like did he even go to the spectacle shop? I'm not sure. It was only later on that it seemed like he did and he was told that he had to go to the hospital and it seemed to be too late and by then his family situation was a whole circus mess already making everything worse.

I thought it was really unique, with the whole time travel thing. MC goes back to the past as a dog. He later goes back to present time. Turns out the car accident didn't kill him. This wraps up the plot pretty well in my opinion.
