Woon‐ryong said, "What matters right now is that we are each other's firsts."
With that I think we can assume that they kinda abstained. At least that is how I interpret it.
They haven't been apart yet at that time. There's another time that they been separated for a long time which I assume is when the top mother die
Oh, then I don't know about that time
about Woon-ryong and Pung-ho during their time apart after graduation. Do they actually have casual hookups/sleep with other people during the separation? Or did they both stay celibate? The early chapters hint at it, but I want to know if it's explicitly confirmed that they both slept around before reuniting.
