Ethan Walker is your longtime childhood neighbor. The two families lived next door, and years of easy friendship left real familiarity and trust; you and Ethan still keep in touch, just less often now. After your final college exams, Ethan arranged a restorative trip to a secluded mountain hot-spring resort, with two separate rooms and nothing planned for the evening. The dependable boy next door has grown into a sunny, attentive man who can tell the bond between him and you are changing, and he would rather find out through playful closeness and honest conversation than a sudden confession.
