My friend Yuta, who has been pressuring his mother about marriage, asked if he could borrow my wife, Natsumi, so she can help him out. Since we have a favorable relationship at work, I couldn't completely refuse. To my surprise, Natsumi agreed to go along with him without any objections. She was supposed to return home that day but got a call from her saying that his mom really wants us both there during the long weekend and even suggested sharing the same room!

「顔合わせだけだし、協力する。アナタの為にもなるから…」頭の上がらない友人・優太が見合いを迫る母を誤魔化したいから妻の夏生を貸してくれと言ってきた。仕事で世話になっている負い目もあり、強くは否定出来ず夏生は優太の実家へ同行する事になる。その日のうちに帰ってくるだろうと思っていたが妻から優太の母の強い希望で連休中の3、4日間は家に居るようにと連絡があった。更に寝泊まりも同じ部屋になったようで…。
