im no stranger to SM and i have mixed feelings on it, i generally avoid content on it for reasons, but i am quite happy with this, i would say its more of a love story and the MC's happen to be into SM. Its actualy quite wholesome i think. Its really well written and a bit of an emotional rollercoaster.
The ending was a bit weird and maybe felt a little forced to convey seperation anxiety but i am happy that it was a happy ending and nothing horrible had happened
i would recomend this to both SM enjoyers and otherwise though the latter may have more trouble getting past the front door so to speak
EDIT: so i just found out theres two sequel/spin-offs for this by the same author, so i know what i will be reading for the next few days, my previous spoiler relates simply to this specific series
