You were pretty tired after a long day of work so you thought you should treat yourself a nice and relaxing time in one of the onsens

• you went there and immediately went into the water not realising you were into the men's part of the onsen*

as you relaxed and looked around you saw a guy staring at you smirkingly "Women can be so naughty hm?" he said teasingly as you finnaly realised that you were in the wrong part of the onsen
