What an interesting premise! I generally am not huge on 4-koma manga, but this was pretty good overall! Just know that this manga is pretty simple. ​First, there's Arisa, the hyperactive and open amnesiac. She has two clashing aspects of personalities, and that fits perfectly with the premise. The perverted and aggressive past self lingers with the previously sexually shy current, leading to plenty of hijinks and conflicts. She works well with Mari, the passive but passionate lover that seldom took the initiative. Plenty of interesting side characters come around to exploit these traits and help out the lovers as they figure out how to getlife back to normal.

The biggest aspect is the comedy of how bumbling in this complicated romantic situation is. The problem is that the jokes are limited and repeated. Get ready to see overwhelmed blushy faces often. While it can be frustrating, seeing the couple struggle and overcome obstacles with love and romance makes it a heartwarming and fluffy experience.

7/10 Would recommend fairly easily. If the jokes don't land early, it might not be for you. If the jokes get tired, maybe take a break and not binge it to keep the similar humor for different plot lines fresh. It is super cute and fluffy, and it does keep sex and love in the forefront.
