Elio is 17 and has hot for the new house guest Oliver.
The first 121 pages are still on how much he wants him. And then dreamed of him being together.
Horny would be a word of choice. Unlike chick-romance, the expression on want and sex is quite honest and out there.
It is fortunate that this is well written, or it would read corny as hell.
Oliver is a nice looking and they were in swim suits.
