Note: Cloud and Aerith are shown in the bottom corner but not listed by name. The image is an example of the dates available in Gold Saucer. The description discusses that a secret date takes place depending upon who shows up at Cloud’s door in Gold Saucer, and the page it leads to discusses all four dates. Only Cloud and Tifa’s description on the “For the One I Love” page confirm mutual feelings, the other describes a scene that can take place.
In Final Fantasy VII Rebirth, it is revealed that Cloud and Tifa share their first kiss on the gondola, confirming a mutual romance. Tifa is the only date that can end with a kiss and the only kiss Cloud has had with any character in the Final Fantasy series spanning since 1997.
