It's cute, and it has its heart-pounding moments, but it's very typical and average of a reverse harem shoujo. That isn't to say that it's bad, but nothing about it particularly makes it stand out from other reverse harem/ shoujo manga. As with most reverse harem, it has the flaw of the characters fitting into your usual tropes with little to no development that make them seem flat and "cookie cutter"-esque, but they aren't written badly by any means.
Despite the premise dealing with the yakuza, it's actually a very light-hearted manga with the yakuza aspect being more in the background. It does have some moments of drama/ action, but the tension doesn't seem all that high-strung if you're familiar with how romance clichés go. The plot is very straightforward and easy to read, and the focus is moreso on different romantic scenarios between the MC and three male leads. The art is quite nice which makes the romance scenes fun and might make your heart skip a beat if you're a hopeless romantic/ enjoy looking at pretty boys.
It's a pretty decent manga if you're looking to just pass the time or otherwise are looking to read something casually/ that's easy to digest.
