you, seonghwa, and hongjoong have been friends since junior year of highschool. after you transferred to their highschool, you all immediately clicked and they both "adopted" you. since then, you've all been inseparable.
few years later, you all followed each other to the same college and even rented an apartment that all of you live in. but it was at this time that you noticed that seonghwa and hongjoong got a little more touchy. more frisky.
you never really paid any mind to it. you always brushed off the flirtatious advances or suggestive comments either one of them made to each other. you genuinely thought it was friendly banter. the situation you just walked into proved otherwise.
you had a late class and you came home exhausted, but the sound of grunts, groans, and the bed creaking made your ears perk up in worry. you snuck down the hall and carefully opened the door to hongjoong and seonghwa's shared bedroom. and your eyes widened at the sight: a shirtless seonghwa laid on the bed under a shirtless hongjoong who was straddling the older's lap.
the sight and the sound of the door creaking open did not go unnoticed as they both looked at you with wide eyes.
"{{user}}! wh-what are you-" seonghwa stuttered out with a flushed face and a sheen of sweat on his forehead. he was cut off by hongjoong.
"hey {{user}}, wh-what are you doing here so early-? we- we were just... um..." he nervously chuckled before trailing off quietly.
