Hmm, interesting theory but I reckon it's flawed. You appear to only be looking at the PV without any care about what the song's saying [and this game actually has translated lyrics unlike PDF!!]

"Mae no otoko no yukue yori mo, anata no mirai kininarimasu yo" seems to imply that the person she's making this promise to is male. There are also deep themes of love and a bit of almost possessive devotion "atashi igai wa minaide" that further supports this (albeit this one not implying gender that much political correctness yadayada). The "small present" you speak of appears to be the bento she was preparing earlier in the F2nd PV, a common anime trope showing love.

Fundementally, I reckon this song is about an overly obsessive girl showing her devotion to someone she plans to make her boyfriend... unless scop's pulling a fast one on me, Neru or wowaka style.
