It's a true rom-com. It has great comedic writing but make no mistake it will give you feels too. Have read this before and I read it again every now and again as a nice pick-me-up. Definitely S-tier.

That gecko scene had me internally screaming. If that happened to me in real life I would be hysterical. This short manga somehow manages to put cute fluffy romance with a bit or angst, some very light comedy, and then a bit of smut all in its few chapters. Although this is overall a light-hearted romance, I mostly remember it for its angst bit because it's written so well. That feeling of going from being on cloud nine thinking you might have a chance at love, before suddenly plummetting into a pit of disappointment and heartbreak when you realize you were mistaken all along. I like angst in small doses and this is just the right amount. Of course, afterwards you're treated to a lot of fluff so it's all gucci.
