Wren and Jay have the same number of unique scenes, so you were probably favoring Jay with your choices and got on his route. If you favor Wren instead, you should see more of him :)
Oh I played both routes! I've been an avid fan of romance games for a while lol I just meant on Wren's route it seemed like we got less of Wren compared to how much Jay we got on Jay's route. But I might be totally wrong! I just really really love Wren :'D he's so frickin cute
