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
This is a fictional story. If there was extra context like condoms being used or a full blood test needed for the story the author would’ve included it. From the way the chapter is written and being able to see mc walking by from the window that the ml is making out with some other dude says enough. i don’t think the author would write it that way if they wanted you to think the ml was an outstanding citizen. Obviously non monogamous relationships aren’t bad, nobody is saying they are bad but I feel like you are blowing peoples comments up and adding context that is not there just to defend the ml

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