Personally, I think the enjoyment of this manga has to do whether you're into Otome Gacha games. Since I have a current addiction to these type of mobile game, I can really sympathize with the main female lead and enjoy the conflicts that the main male lead encounters.
I also enjoy a good male tsundere, so she really gets me on a deeper level. If I didn't relate to her on a lizard brain level, I'd probably find the conflict lame or unappealing.
There isn't any real strong conflict so this is a nice light, fluffy read that I think Otome Gacha lovers will like. If you're not into that type of game, it'll probably hover over a 7 or 6 since it's enjoyable, but won't leave a lasting impression.
