Immediate response is One Room TA (BL), if you haven’t caught up already. It’s not merry the whole way through and, honestly, begins with an unimpressive ‘he’s so quirky and weird’ but. gods. fucking hilarious anyway, even if the genre isn’t predominantly comedy.
give it a few chapters if you will, genuinely guaranteed happiness, good luck!!!!
One Room TA (one of the most effortlessly funniest and wittiest bls with great romance and a handful of angst)
Circuit Breaker (comedy mostly comes from the mc being utterly fearless, unfiltered, unpredictable, narcissistic, and unhinged against a backdrop of a relatively normal cast. read this last night and was genuinely LOLing and wheezing)
Love Advice from the Grand Duke of Hell (mc summons a demon from hell to help him pursue his crush. one of the classics and funniest webtoons with many iconic scenes)

What is the funniest most UNGODLY hilarious manga/manhwa you know? Im talking about weezing laughter where u make weird high pitched noises while u cover your mouth and your face freezes with tears in your eyes and a smile so wide it stretches your jaw and hurts please i need happiness and i need it now
