It pisses me off too. I liked the story but this whole moment in garden just turn me off.
I felt the same! and i also hate that it wasn´t very clear what really happend when they where fishing, specially because the boyfriend of the gardener´s friend said to sumito that they were cheating them! I dislike that part the most.
Yeah, it irked me in the beginning too, but I try to see a connection between the "No way" and the "Isn't your boyfriend good enough" even though it is on the next page.
I reaaaally loved the story. But, what really pisses me off was... When the Gardener's friend asked. If Sumito wasbetter in bed than himself, and the gardener said "no way."
