My gosh I feel like the people in the comments and I aren't reading the same thing. Of course yeonwoo's action would look manipulative, but in all honesty he has trauma and ptsd all his life, which affected his way of thinking. Think of it as a child that wasn't able to grow properly. My baby already has a lot of things to overthink and overwhelming anxiety. The only thing that made him happy is mc, and you're telling me his manipulative and red flag? Doesn't that mean that mc should be a red flag too since he used yeonwoo's luck to make his bad luck nullified, and he even admitted it on himself before realizing he like yeonwoo.
