The man's surprised reaction to the woman's name, which sounds like 'Klyma' (climate).

The ad opens with a close-up of a man looking surprised, then cuts to a woman with glasses who introduces herself. The man is confused by her name, which sounds like 'climate change'. The woman explains she is the sister of 'Klyma Wandl' and that she is moving in with her. A third person, dressed dramatically and standing on clouds, appears and claims to be an 'under-renter' and that the deal is temporary. The woman then suggests a 'makeover' for the apartment, which the dramatic person rejects. The ad ends with the Yello logo and slogan.
