This is your typical high school romance all about lap pillows. The MC is your average guy who enjoys sleep like no other. He uses every chance he gets to sleep but there's a problem. His cute kouhai always interrupts him whenever he's alone. That's my main issue with the manga. The manga tries to say that her interrupting the guy's sleep is cute and adorable but it is not. Literally, the MC doesn't even get the chance to sleep peacefully caus she always interrupts him. The MC is not even assertive and has no backbone. He's clearly bothered by it but he does nothingabout it. He lets her have her way with him too much and even falls prey to her. I find the kouhai really annoying. Let him sleep in peace.
