Her: Thanks 🙂
Her: Nothing too serious I’m just here for a good time. This message can be interpreted as her looking for and one night stand (ONS).
Her: What about you?
Her: You’re easy on the eyes too

Aha thanks girl 😘And me too, trying to have some fun and going with the flow
 This message matches her energy. It doesn’t scare her off by saying he’s looking for something serious but it is also not explicitly looking for a ONS. It is deliberately vague.
