i will always love you
A song originally written by Dolly Parton and released June 6, 1974. Its most famous rendition was by Whitney Houston, who recorded a cover version for the 1992 film "The Bodyguard" starring Kevin Costner and herself.
This song has achieved a memetic status in Japanese Internet fandom as a romantic theme, and the stretched out "And IIIIIIIIIIIIIII~" will often be referenced in the comic or picture.
