Just because Dongho doesn't have any experience in dating and happens to meet someone who's used to hooking up doesn't make their relationship bad. Dongho's innocent sure, but I'm pretty sure he's old enough to know what he's getting into and isant mentally 5 years old.
Yawhi is a rapist and Cain is a adorable guy who actually cares for him. It's stupid that he's even taking dating yawhi into consideration
