<p>I genuinely had a fantastic time reading this! I went into this volume with absolutely no expectations, and it left me beaming. This manga features three brief romance tales, two of which revolve around high school relationships. Overall, the stories were engaging and presented with straightforward storytelling that allows for swift immersion into the romances. While the beginning of the second romance comes off as slightly unsettling, I appreciated the ultimate message and its resolution. The last story felt somewhat hurried and might be the least convincing among the three. Personally, I believe the author possesses a charming art style and an excellent sense of rhythm, though occasionally the page layout makes it challenging to follow the narrative. Given that it consists of three short stories, the plot development is a bit rushed, and some characters lack depth (sometimes falling into clichés), but their brevity is precisely what makes them so thrilling!</p>
