Why do romcoms always treat confessing like some formal procedure you need to go through to officially date? Like, these two dumbasses already made it pretty clear to each other they have mutual feelings. Both know it, both want to date each other. There is quite literally nothing stopping them from becoming an item other than this dumbfuck notion that they can't do it until one of them goes "I hereby profess my feelings of love for you and humbly request to enter a formal romantic relationship with you".
There is no fucking point to this shit other than to drag things out and milk this "will they, won't they" (they obviously will) bullshit that no one fucking enjoys.
