Also it doesn't show but you can def interpret it that way
Adult dog licks her lips and both Adult Cat/Dog touch MC/FL hair/face next scene is the RV jumping and them walking back to their own car with blushed faces, huffing as if out of breath and shaky legs like a baby deer, so yea I think they kissed as a lesson to never go into a strangers car
either way the main focus of the series is MC/FL and its not even the yuri its the idea of camping and how to make camping fun WHILE tackling the past trauma aka MC's RIP dad and FLs hospital situation aka how we saw her this ch with her being sad that her ex friends where jealous she gets to still be a 2nd year not knowing what she's been through etc
