What was supposed to be a girls only beach trip aboard Yumemi's Probability Space Hypervessel was quickly changed to include a fourth member when Rika insisted that she'd be allowed to bring Farmboy-kun (who is DEFINITELY not her boyfriend!) along. Yumemi took a liking to Farmboy-kun and tried to flirt with him. Despite not being very interested in anyone but his temperamental engineer, Yumemi's relentless advances did eventually lead to him caving in and having a bit of fun with her, maybe something about her reminded him of Rika? Either way, no lines were crossed, so everybody came out alright... I think.
