Best watch as stand alone

For viewers who never watch the prequel, The story is engaging at the start, but from middle to end feels a little dragging. best to cut short into 24 eps. the pairing is okay, but a little boring, because there is no real conflict.
Acting for the leads not so explored because of character set up, but for supporting actors its really good.
music : I really don't fully focused hearing it, but i heard the prequel song has been recycled so its a plus for me
Overall : it's a little tepid for me.
