I keep a list for when the world feels heavy. Some standouts are 'The Flatshare' by Beth O'Leary—the humor is so gentle and springs from the characters' awkward, lovely situation. It's not about zany antics, but the kind of quiet, observational wit that makes you smile because it feels true.
For something with a bit more playful chaos, 'Boyfriend Material' by Alexis Hall is a delight. The banter is sharp but never cruel, and the messy families and public mishaps are so over-the-top they loop back to being comforting. You just know everything will work out in the silliest, most heartfelt way possible.
Honestly, I think the real trick is finding authors who write kindness into their characters' bones, even when they're bickering. That underlying warmth is what makes the happy ending feel earned, not just tacked on.
