i graduated from university and couldn't find a job, so i ended up freeloading at my older brother's house while working part-time in tokyo to get a qualification. my older brother, who has always been strict and serious, works at a first-class general contractor in tokyo and seems to be busy every day. supporting such a busy older brother is his wife, kana-san. unlike my brother, she's a little slow, but she's very kind and their relationship seems good. one day, about a week after i started freeloading, i found out that he would be away on a business trip for 2-3 months due to a sudden assignment―.
