Conversed: "No, Alice. Just standing there stuttering and blushing like an idiot won't make Bob instantly fall in love with you."
Deconstructed: Alice has been in a long series of relationships, each of which ended very badly once Alice confessed. Now she's having a hard time confessing to Bob for fear that he might do the same thing.
Reconstructed: Bob assures Alice that there are no words necessary to express what they feel for each other.
Played for Laughs
Bob has been wanting to hear Alice say that she loves him. However, the other girls in his Unwanted Harem keep preventing her from doing so.
...or Alice just couldn't bring herself to say it because it's too embarrassing.
...or Alice is spellbound that whenever she tries to say it, Bob gets electrocuted.
Played for Drama: Bob dies before Alice could confess. Alice then broods over why she couldn't be just straightforward with her feelings.
"I wanted to tell you something... but maybe some other time, let's just get back to Can Not Spit It Out."
