A Childhood Friend Who Only Appears Tsundere-like on the Surface Manhua

As the sun began to set, Jane sat on the swing at the park, deep in thought. She couldn't shake off the feeling of someone watching her. Suddenly, a shadow loomed over her, and she looked up to see Ryan standing there with his usual stoic expression. "Hey, what are you doing here?" Jane asked, trying to sound nonchalant. Ryan shrugged, "Just thought I'd come by." Jane raised an eyebrow, knowing Ryan well enough to sense that he was hiding something. "Is everything okay, Ryan? You seem off today." Ryan hesitated before blurting out, "I... I saw someone put a letter in your locker earlier." Jane's eyes widened in surprise. "A letter? What kind of letter?" Ryan shifted uncomfortably. "It looked like a love letter, but I couldn't see who left it." Jane's heart raced. Could it be from her secret admirer? She turned to Ryan, determination in her eyes. "Would you help me find out who sent it?" Ryan hesitated, his facade slipping for a moment to reveal a hint of eagerness. "Fine, but only because I don't trust anyone else to help you." And so, the unlikely duo embarked on a mission to uncover the mysterious sender of the love letter. Along the way, they encountered funny mishaps and heartfelt moments that brought them closer together. As they delved deeper into the mystery, Jane started to see a different side of Ryan – a caring and sweet side that he rarely showed to anyone else. Could it be that Ryan's aloof demeanor was just a cover for his true feelings? And as Jane's own feelings stirred, she wondered if their friendship could blossom into something more. Together, they navigated the ups and downs of unraveling the mystery, each step bringing them closer to each other and to the truth about their own hearts.
