so i just learnt about that reddit tifu story where the guy spent 2 years fucking his gf to the beat of a song and even after she told him she hated it and banned him from putting it on during sex, he would still thrust to the tune playing in his head (and she recognised it)
naturally, my mind immediately went to cumplane
imagine. they were secretly friends with benefits in their first life when they were both in college (pre-pidw days). xiang fei would put this song on every time they fucked until shen yuan flat out told him he hated it and xf's taste in music sucked and the song's rhythm isn't even good to papapa to. devastated, xiang fei, a child of the 21st century, complained about it on socmed (wholeheartedly believing that with china's vast population and him posting from an anonymous account, there was 0 chance anyone they both knew in real life would recognise it)
unfortunately for him, shen tang, a fan of "today i fucked up" stories and frequent visitor of the forum xiang fei had posted on, immediately recognised the song as that really obscure one her brother's college friend mentioned when he came for dinner a couple of weeks ago. the ages and other details from the post also matched everything about her brother and his friend
naturally, shen yuan is incredibly flustered their definitely-not-gay fwb relationship is now out, breaks up with xiang fei and blocks him everywhere. xiang fei is heartbroken, and it's only years later - when he starts writing a stallion novel - that he finally, kind of, moves on from shen yuan. thankfully, a particular hatereader of his novel is a pretty entertaining distraction from ruminating about his past fuckups
cue transmigration, peak lord meeting. yue qingyuan is giving a particularly dull speech (something about health and safety, probably). xf!shang qinghua doesn't even notice when he starts to tap that song's melody on the table's surface with his fingers as his mind drifts back to his very first crush from college....
it's been years since their fwb relationship ended but sy!shen qingqiu could not mistake that rhythm for anything else! how many people in the world had THAT bad of a taste in music AND would tap that tune out when they were bored? he only knew one!
