Is it maybe this one?

Ah! Yes! Thank you!!
It was a short BL (5-6 chaps) and it was based around the Uke meeting the Seme at a train station(??) and going on a hot springs trip with him, but the Seme isn't a stranger and is instead a kid he used to know in his hometown
Uke finds out when he sees a photo of the Seme when he was younger(??)
Uke may have been an influencer and that's how the Seme found out where he was?
Any help is greatly appreciated!
