"Could this be... the cute-hating-suicide-stun syndrome?"

The male protagonist (player) suffers from a rare disease that causes him to faint when he sees something cute.

It wasn't easy to survive in a world overflowing with cute things.

Two years have passed since I began my life of seclusion, and just before graduation, I receive a call...

 "I'm moving when I graduate. Should I at least say hello properly?"

Hong On-seol, my only best friend, whom I had a crush on for two years.

There are still feelings that I have not yet been able to convey, but that I must convey.

Three days before graduation, will you be able to return to school and successfully complete a risky confession?

<Harmful to the Heart> is the first work from Studio Digital Cakeshop.

For all the cute things in the world, for the heart that feels even the smallest things big,

And it's a sweet visual novel about love and honesty.

 ʚ♥ɞ Illustrations full of crazy cuteness ʚ♥ɞ 

The main heroine, Hong On-seol, is designed to be a powerfully cute character, so intense it's impossible to escape once you see her, while also infusing her with a gentle warmth. She loves cuteness more than anything, and countless other cute characters entangled around her are ready to become the perfect supporting characters in this messy, loose-knit romance. Be prepared for a game over, but be sure to get entangled in the lovely world of "Harmful to the Heart."

 ʚ♥ɞ  An unpredictable and risky choice  ʚ♥ɞ

Before reaching the ending, countless moments will test the player. One wrong choice will result in a game over, and players must drag the protagonist, who is gradually becoming a pufferfish, by the collar until he confesses. From simple multiple-choice puzzles to heart-pounding time attack choices and exhilarating click-and-go action, we wish you luck in the face of endless peril!

Never let your guard down until the very end!

The game will be played over three days, and as soon as the game ends, you will return to the starting point of that day.

Please protect your passionate heart that never gives up for love!

 ʚ♥ɞ   A collection of... items that make you greedy   ʚ♥ɞ 

Good choices will not only help you avoid danger, but also increase your favorability rating and allow you to collect adorable CG illustrations. Let's create memories with Onseol as she displays her cuteness in various situations and appearances. Repeatedly fainting may even unlock achievements that lead to special storylines.

 Welcome to the heart-pounding, cute survival show, <Harmful to the Heart>!
