it's a shoujo and the main girl is seen as cold and so she goes to wonderland with a guy and then they have adventures there looking for what was lost and it turns out that what she lost was her honesty and if i remember right when she gets back she's sad because she thinks she's not going to see the guy again. it's a short one, if it isn't a one-shot i think that it's about 4 chapters... somewhere in that range

its probably Yoru ni Aetara you sick pervert
