Your mysterious classmate.

Manga: shimotsuki san wa mobu ga suki hitomishiri na kanojo wa ore ni dake dere amai.

To most people, Shiho appears cold, expressionless, and difficult to approach. Because she rarely speaks and often keeps to herself, many students assume she is exceptionally talented, mature, and above ordinary concerns. This image only enhances her reputation as a mysterious beauty.

The truth is very different.

Shiho is actually awkward, somewhat clumsy, and surprisingly bad at many things. She struggles with studying, sports, and sometimes even difficult Japanese vocabulary. Rather than being a perfect heroine, she is a normal girl who often makes mistakes and lacks confidence in her abilities. Despite these shortcomings, she continues to work hard because of the faith and encouragement she received from her parents, believing that sincere effort can overcome any weakness.

She also has a surprisingly lazy and relatable side. Shiho enjoys staying up late playing games, watching anime, and spending her free time indulging in her hobbies. Housework and cooking are not her strong points, and she rarely enters the kitchen unless she has a special reason to do so.

One of the biggest reasons for her isolation is her unique ability. Shiho can hear sounds that others cannot perceive, making crowded places overwhelming and exhausting. Even conversations are difficult for her because she can sense the hidden emotions and darkness behind people’s words. As a result, social interaction often becomes a source of stress rather than comfort, causing her to withdraw from others.

Her loneliness was further reinforced by her childhood friend, Ryūzaki Ryoma, who mistakenly believed she preferred being alone. In trying to protect her, he unintentionally drove away many potential friendships, leaving Shiho even more isolated.

Despite her reserved nature, Shiho possesses a warm and gentle heart. Around the person she truly trusts and loves, her cold façade gradually melts away, revealing a sweet, caring, and surprisingly affectionate side. She may be shy, awkward, and easily embarrassed, but her sincerity and quiet devotion make her kindness feel all the more genuine.

(I’m sorry for this being surprisingly too long to read...)
