Conditional wherehas with Laravel Eloquent

I have one similar (area) value in two tables one and two and these two tables has relation with main table master. At a time, the master table will be having data in one relation only and the other one will be null.

With this architecture, I have a search page where user can search any values related to these tables and the search fields are placed with AND condition.

Here, if user enters some value for area I need to check the area value exists in any one of the tables (one or two) without breaking the AND condition. Tried the below code but it is breaking AND rule and considering OR. Any suggestions to fix?

$result =  Master::where(function ($query) use ($request) {
    if ($request->filter == true) {
        $query->where('user_id', Auth::user()->id);
    }
    // other conditions here
    if (!empty($request->area_from) && !empty($request->area_to)) {
        $query->whereHas('one', function ($query) use ($request) {
            $query->whereBetween('area', [$request->area_from, $request->area_to]);
        });
        $query->orWhereHas('two', function ($query) use ($request) {
            $query->whereBetween('area', [$request->area_from, $request->area_to]);
        });
    }
    // other conditions here

})->with(['one', 'two'])->paginate($request->item);
