Who is the ML? Its not Oswald.

Wait... What??? I did not see that coming at all

Neither did I, I went searching for spoilers because I had a bad feeling about Oswald, and all the hearts were black or 1 heart for being friends and well these told me it may take a few years to finish. I got my spoilers that for sure including the ML.

Same he was giving red flags good thing he wasn't the ml.

But the way it's depicted in the manhwa I really thought it would be him

Yeah, don't get me wrong I've read toxic romance before but when you have a FL completely afraid like that, it's normal reserved for the villains or those trash family member.
