The end was so-so for me. In fact, the entire last volume was weak. The fever and injure has been used tons of times. The "I am moving away tomorrow" is so cliche. Everyone ending with other from the same group was predictable. The "XX years after" was ok-ish. Nevertheless, as a whole, I enjoyed the manga and I liked almost all characters. It was funny without being hilarious, it was kind of sweet without being corny.
