The Tunnel to Summer, The Exit of Goodbyes

Kaoru Tono is on his way home from school when he wanders into a tunnel one day. Rumor has it this tunnel can grant you any wish-but if you spend too much time there, you will lose many years of life. What he finds there is not quite what he expected-particularly as he's exiting, and he finds, waiting for him, the troublesome new transfer student Anzu Hanashiro.
