First of all let's see what a " Collector" is, according to psychologists.

For people who collect, the value of their collections are not monetary but emotional.
The collections allow people to relive their childhood, connect themselves to a period or to a time they feel strongly about. Their collections help them ease insecurity and anxiety about losing a part of themselves and to keep the past to continue to exist in the present.
Toh thinks he will never be worth of Nuea love. He thinks he does not have anything to offer, that he isn't something special, no good looking, shy, nerd.
So he watches him from afar. Collecting mementos of moments that are precious for him.

Collecting may provide psychological security by filling a part of the self one feels is missing.
When one collects, one experiments with arranging, organizing, and presenting a part of the world which may serve to provide a safety zone, a place of refuge where fears are calmed and insecurity is managed.
In his room, Toh can openly fantasize about being loved back. He is bold and brave, he approaches Nuea.

Items in a collection are neatly organized, maintained, and presented or manipulated with ease.
(If a collector of 1000+ trains wishes to find a particular specimen from their collection, they can find it easily. )
Collections are often catalogued, sorted, and objectively maintained like books in a library.
Toh mementos are kept like treasures, handled with care and perfectly organized.

This is not a dangerous behaviour.
Although it still has its counterpart that is scary, creepy and dark. IT' S NOT THE CASE IN THE SERIES.
So judging Toh like he was a serial killer,( as someone did in their review) is really too much.
It's true he is a controversial character and his "obsession" might result uncomfortable but, please give him time to develop, grow and change.
Nuea seems to be aware and know a lot about Toh and his particular interest for him and never embarass him, or treat him harshly.

Please, don't just drop the series at the Synopsis or the 1st episode.
