Yoon did rape the alpha, but I don't think he wanted to? In chapter 3 I'm pretty sure it meant that Yoon gets affected by the pheromones, and when the alpha attacked him due to his rut, Yoon was crying and fighting back, but couldn't cause he was drunk. Also when he woke up he was in shock and didn't remember anything, he wasn't in the right mind. And the "I won't touch hyung, never" line in chapter 5. But idk he's still in the wrong imo
THE FACT CHARLIE NEVER WENT BACK TO HIS PARENTS and it was such a fitting ending for the doctor, who could've lived happily with Mindy and their child to suffer eternally for his inferiority complex living in hiding forever
