After waking up, Riki learns from Yuiko that she was taking care of him while he was asleep and cannot shake the suspicion that the whole situation has happened with them in the past. Some time later, Kyousuke and the other boys point out that Riki is behaving strangely since his last encounter with Yuiko. (Source: Wikipedia)
