I think this is like my second review for manga because I'm seriously enjoying this so far! The manga is well thought out and the whole "Rental Girlfriend" thing is a nice thought way of getting turning it into a romance manga. The romance is slow and you'll almost find no extreme romantic moments between the main characters at all which will make you feel all lovey-dovey. As you read on you kinda think "Damn this is gunna turn into a harem" and honestly I wouldn't be surprised if it ended up that way lol. The art isn't over the top amazing but it's average and the characters are decent with the tsundere towards the beginning and then it slowing down as it goes. I don't know if I'll find myself back reading it after today simply because I'll forget about it because it's not finished.. but I definitely think this manga needs an anime adaptations to top it off.
