For the record, STIs get transmitted through bodily fluid contacts, alright? Not just sex! Also kissing! So before you defend someone who sleeps around and kisses different guys in a span of a day or even a week, make sure not to include the argument of safety protection against diseases—because you'll clearly lose.
...but these people (fictional at that) never even mentioned having full panel blood tests or even checking themselves for diseases. furthermore, korea doesn't even do mandatory STIs check up and is completely voluntary—so no, we can't assume the reckless slutty top is secured in his health and is very clear on STIs allegations until you prove us wrong and there's some proof in the future chapters

HELP WHY IS HE MAKING OUT WITH ANOTHER GUY bruh he def has diseases with how much he sleeps around omg
