With how problematic this show is, I like it more than I should.
To be clear, I think Saint and everyone he worked with did a marvelous job. Especially for his first time as a producer. It was probably really hard. It's always hard doing things you've never done. But Saint has a lot of experience as a BL actor. He knows what people like to see. And I think he's probably sick of some of the same tropes that we as the audience are, which might be why he picked this story to turn into a drama. I think this story is actually very unique. It's about a stalker who is actually not insane. My personal evaluation of Toh is that...he could be worse. He could definitely be better, and I really wish he was, but he could be much worse.

When we think of stalkers we imagine a person who follows their target around, spying on them. Someone who hurts anyone who gets close to them. Peeping toms. Insane people who kidnap the person they're obsessed with and r*pe them. Send dead things in packages to their significant other.

The difference is that yes, Toh is creepy, but he's only harming himself by doing what he does. He won't hurt Nuea or anyone he gets close to. So in my opinion, his feelings for Nuea are less of an obsession than what you might see from a typical stalker, because he does love and care for Nuea. He's willing to stay away from him even though he wants to be close. He's also aware that what he does (collecting things) is weird. He feels bad about it, but he doesn't seem to be able to help it. I would argue that it's a mental illness, in the same way that hoarding is, where you know it's bad for you, but you can't help it. You know you should throw that thing away. But something won't let you.

I'm not justifying his behavior. There is something seriously wrong with a person who digs through the trash for a soda can that was only touched for less than a second, who collects crabs, tangerines, a pig's head, a bandaid wrapper, a pillowcase and popsicle sticks and then vaccuum seals all those things and keeps them in boxes. Who has a whole wall covered in pictures of his obsession. Who cares more about getting a picture of someone kissing him than the fact that it actually happened.

To be honest the series should have ended with Toh seeing a specialist or something and getting help for his problem, and throwing all that weird shit in the garbage. I actually think it would have been funny if Nuea had secretly done the same thing. I mean he's as freaky as Toh so it would not have surprised me.
