There is probably nothing more anti-romance than a couple on a verge of a break-up; when the spark is not just gone but harming both parties (in this case, one more than the other). A fight is how the story starts, full of resentment and misplaced hurt. Setting expectations that behind the bright UI of the entry, darkness looms ahead.
And yet, this is not the path the story takes. It does not wallow (for long) in the misery of hurt feelings, despair over failures, or doubles down in the hurt in the hopes to salvage the doomed relationship. Instead, it takes the path of healing and love - for oneself and others but with a healthier view and supportive friends.
Love is an action you choose to do, how you show people you care about them.
As a final point, the formatting of the story inside chat rooms was so fitting. Each user had their own distinct voice, that barely needed the username to know who was writing which message. The addition of typos during emotional moments, especially for Sylvia, were a great touch!
