I can't say it was sad for me, just confusing. Who was the second kei? That in its self is a huge question that never even got touched on so it left me to feel disconnected from the story. But it was interesting just don't recommend to others unless you like a story were you don't get a clear end.

The second Kei was a delusion, he never existed. He was a representation of what Akutsuga wanted from the real Kei, or I should say, what he thought he wanted. This isn't uncommon with people who have emotional break downs. Likely, from the outside, Akutsuga would have appeared to be moping at home, sleeping and masturbating a lot. He had cloistered himself inside his own fantasy. You might understand this behaviour better if you imagine it as a person who becomes obsessed with a game character and spends all their time playing the game just to be "with" the character they adore. In this case, the character is Kei inside Akutsuga's mind. Obviously, this "character Kei" is within his grasp and the real one is not. Though Akutsuga claims that the "character Kei" is real, there is no proof of this. No one else but Akutsuga sees, hears or touches the "character Kei". Basically, this is a story of what happens to a fragile heart and mind when feelings are deeply suppressed. This happens IRL more often than anyone would like to admit and they rarely end well. The most common outcomes tend to be attempted or successful suicide or homicide with the victim being the object of the obsession. When all is said and done, the moral of the story is "Don't bottle up and suppress your feelings." Even if you have to talk to a total stranger at a bar, a therapist or your pet, let those feelings out somewhere safe. The human psyche is like a pressure cooker, if there is no way to "vent the pressure" it will explode and the clean up will be a nightmare.

Diets are not good. If not done correctly. You cut back on food which makes your body think it's starving so it then starts to store it more. So even if you get the shape you want form the diet once you get off it you gain weight way more easier cause it's storing for the next starvation. I won't say "be happy with your body" if the way you take care of it is decreasing your life expectancy. It's great to want to be in better shape, but there are correct ways ro do it. Like eating correct portions, going on a 30 minute walk a day, getting rid of sugar products. So I do agree it is fine to want to look good for your lover as long as it is in a healthy way.

True. That's why other says that diet is a myth and that no diet regime in this world is effective or at least have an effectivity that lasts long. We also have to take consideration the body type and the metabolism of that person. And each person is unique so does their needs and what is effective to one might not apply to another. Totally agree that it's okay to loose weight for ur lover or for yourself but in moderation and ofc in a good way.
I don't think anyone should be with nobody introduced so far in this story. They need to fix themselves before they get with anyone else.
you speak the truth, they gotta check themselves before they wreck themselves (and each other, goddamn-)
