Music video
The music video features some captions at the beginning describing Ai's love for a man she misses. After this introduction, there is Ai talking into a camera as her 'boyfriend' joins her for her birthday. It is filmed as an 8-minute mini-drama. The storyline features a happier Ai through videos and pictures taken, a crying Ai holding her dead boyfriend's hand at a morgue/hospital, and then a melancholy Ai against a dark background. The video ends with a flashback of Ai and her boyfriend at night walking the streets.

An animated version of Daisuki da yo features Ai's bunny characters, LOVE and LOVE's male counterpart. It shows scenes of a melancholy LOVE in a pink room reminiscing the times dancing and going motorcycle riding with her lover.
