I think this is the same guy from Good Day because of the start of the song being in Good Day (this works with WTTH & TFAR because WTTH is about TH at Marvin's while TFAR is about Marvin himself) so I think the girl he misses is the same one from that song "Come here and sit down I'm so glad you even really truly came" and "We can even go and take a walk or something like that or something like that" suggest they're on a date which means that here in Greener it didn't work out as also seen in Good Day with "I thought you knew I knew but why and bye and why and bye and bye. I wanted you to know I thought you knew my why and bye and why"
