'Strange Eloquent belongsTo() return null. Foreign key property being displayed but not accessible

Environment : PHP 8.1.4, Laravel 9

Eloquent Model : Market Model, Sequence Model

Sequence Model belongs to Market Model.

// Sequence.php
public function market()
{
    return $this->belongsTo(Market::class);
}

Market and Sequence table has each data properly..

Problem is, Sequence model cannot access its market properly. It looks like $this->market() works fine but $this->market returns null.

// Some method in Sequence.php

private function loadCollection(): CandleCollection
{
    dd($this->market(), $this->market);
    return $this->collection = $this->market->createCandleCollection($this->label, $this->size);
}

When I dump $this->market(), it returns BelongsTo object and $this->market, it returns null.

Also, $this->market()->toSql() returns

select * from `markets` where `markets`.`id` is null

Strange thing is, it works actually fine just yesterday and I didn't change its code....;; I believe unknown side effect can cause this but I never experience those kine of issue. Any insight help...

Sorry.. I just found that there is an empty method getAttribute($key).. and coworker said he made some joke.
