Frankie encourages Brick to ask Cindy out for ice cream on Valentine's Day, which Brick does, but he then panics when Cindy suggests that he should kiss her at the end of the date. Devin Levin forbids Axl from getting her anything on Valentine's Day, a holiday she claims to hate, but Axl isn't sure if she really wants something. He compromises by planning a special day for the two of them to celebrate "National Radio Day" on February 13. Meanwhile, Darrin has arranged a special Valentine's Day scavenger hunt for Sue. The hunt ends at a tiny house which Darrin says he bought for the two of them. He then shocks Sue with a marriage proposal, complete with a ring.
