Eventho s2 wasn't as good as s1, i would still recommend you to read s2.
s1 is all about a haunted mansion, the ghost and solving mystery. Not gonna lie I was a little disappointed bc I first went in thinking the ml can turn into a wolf hence the name "winter wolf" and the ml's eyes ╮( ̄▽ ̄)╭.
In s2 you will get to see the ml groveling for fl's forgiveness, them building a live together, unfolding childhood traumas and very little detective Hofflander's appearance (this side character is very endearing to me because of how clumsy and adorable he is).
Overall, both s1 and s2 have very solid plot line and the ending is not rush at all. For me, i just prefer the paranormal activities and 2 people stuck in a haunted mansion during a snowstorm of s1 more. Happy reading :))
Im so invested in detective Hofflander's love life (▰˘◡˘▰)
