Na its more complex....cause the way uncle said minyoung is more like him which means they are both have unhealthy obsession with their partner as we saw in the beginning how minyoung is. So uncle's unhealthy obsession might be the reason why she killed herself. Cause u cannot escape a crazy obssesive partner and killing seems to be the only escape so THATS MY THEORY

Who all thinks miyoung’s uncle killed his wife and made it look like a suicide?
At first, I took it at face value—she committed suicide because he was so obsessive towards her that that was the only way she found escape. But the constant comparisons between him and miyoung and the fact that miyoung was going to strangle Cheol with a rope after cheol ran away from him post outing… hm
I don’t know what the papers say under the sticky note but they could’ve been signed divorce papers or restraining order? Lmk
