It's decent; it’s somewhat like a Japanese take on that Korean thing, but it stands out on its own. The focus is more on the romance, which the title already suggests. It has less of the Korean arrogance and face-slapping that I personally find distasteful. There's also less emphasis on power climbing and becoming a god; instead, it's more about becoming more versatile.
The protagonist's power doesn’t allow him to become a demigod. The fake versions of the skills he copies are less powerful and he can use them less frequently than the originals, but he compensates by having a wider variety of skills. It’s like being a mage—he has a strong skill he can use once, but also several medium-power skills he can use more often. His ability is quite strong and is on the better side of the spectrum. Essentially, his power is a jack-of-all-trades, master-of-none approach. Most of the skills shown so far are attack skills, so I don’t know if there are any healing skills, but I assume there are, given that he has a mist skill (like a smoke grenade). I also assume he isn’t on the front lines, as most people only have one skill, and you need to kill monsters to level up.
Basically, it’s about a poor guy getting stronger, having his potential recognized, and becoming happy and satisfied with his "partner," or girlfriend, after saving her. She’s around his power level when they meet.
