Old Summer's Memories Of An Overworking University Graduate

Following an accident resulting in the death of his family when he was away studying overseas, Haruki has cut all ties to his past and has been focusing on the future, going so far as to block out all things reminding him of his past. He's landed a job and for the past 4-5 years, have been overworking himself.

Now, he's on a business trip/vacation back to his hometown for the summer where memories are in abundance.
