Pick-Up and Chase (гет)

After she accidentally trips into Adrien and apologizes about "falling for him," Marinette learns that he's no match for cheesy pick-up lines--whether they were unintended or not. And while she finds it flattering that he turns into a flustered mess with only a few words, Marinette comes to regret making him uncomfortable. That is, until she learns he's Chat Noir. At which point the phrase "just deserts" becomes a permanent fixture in her everyday plans.
A story in which Adrien is flustered, Marinette is smooth as glass at dropping lines, and Chat Noir gets the romance he was always asking for--even if he doesn't quite know how to handle it.
