”You’ll die if your heart flutters” — hearing such a setting, some might be puzzled about what kind of otome game this could be. However, that is exactly the greatest charm of ”Glass Heart Princess.” The protagonist is a perfect young lady with no flaws. Appearance, intelligence, family lineage—everything is extraordinary. Yet, at the end of her high school life, she is suddenly struck by ”Glass Heart Syndrome,” falling into an impossibly thrilling situation where her life is at risk whenever her heart flutters. She wants to know love, but if her heart beats too fast, she might die. The romance that unfolds amidst these conflicting emotions will tighten your chest with laughter, tears, and unexpected heart-pounding moments.

The uniqueness of this game lies in the constant tension of having to pursue love at the risk of your life, rather than just spending sweet time with handsome men. In typical otome games, the heart-pounding excitement is the center of pleasure, but in this work, it directly links to risk, so players must always face the ”strength of the protagonist's heart” as they progress. To combat this strange disease, she chooses the eccentric method of ”daring to fall in love to train the heart” based on a doctor's advice; this development is so novel that you’ll find yourself drawn in more with every page you read.

The Nintendo Switch version also includes the sequel, ”Glass Heart Princess: PLATINUM,” as a set, allowing you to thoroughly enjoy the subsequent episodes of the couples united in the main story. These after-stories, depicting the so-called ”beyond the happy ending,” not only reveal new sides of the characters but also make you feel as though your bond with them has deepened. Moreover, it is perfectly satisfying in terms of volume, featuring extraordinary dates at a tropical resort and even ”Triangle Dates” spent in a love triangle with a rival. In particular, the Resort Edition, where the atmosphere changes completely depending on who you spend time with, is the perfect reward part for when you want to be released from daily stress.

Furthermore, the ”Side Stories” told from each character's perspective are not to be missed. The inner voices and determinations they usually don’t show are carefully chronicled, greatly deepening your understanding and affection for each individual. This mode, which allows you to touch upon their true feelings and the thoughts behind small gestures that couldn't be seen from the protagonist's perspective alone, is a luxurious setup that packs in the true essence of otome games. It adds depth to the story, and as a player, the fun of immersing yourself in the world is sure to double.

Gaining secret attention in this work is the story of Satsuki Chiga, the maid who appears as the protagonist's attendant. In the ”Satsuki Arc,” triggered by a ”certain incident” that occurred on her birthday, the content delves into her personality and background. Turning away from her quiet position as a servant to stand at the center of the story, her expressions and strength provide a depth that feels different from anything before. With surrounding characters supporting her, it is impressive how dense the episode is—almost too good for just a small spin-off.
