The uke is kinda sus, I'm pretty sure he was the one who pricked the seme with some libido poison and coincidentally get one of the bugs there, as well as put something in the milk tea... maybe he thinks the seme is not interested in him anymore (reminds me of another webtoon where long time lovers become awkward asf then when they break up the seme switches with his younger self and they kinda rediscover love)

i think it’s this one https://www.mangago.zone/read-manga/this_ending/
Oh man she should have just told him, it's like drama foreshadowing
