Iketani missed an opportunity to see Mako-chan and hates himself for never calling to say he was sorry. By chance, he runs into her 6 months later, and the situation is awkward. Iketani does not have a chance to talk, but both want to talk, so they arrange a second meeting. Iketani goes to the meeting place early, but an old man was left behind from a tourist bus, and asks Iketani to catch the bus for him. Iketani, being a nice guy, can't say no.
