A youthful ten-year promise

Chapter 423 The Equation of Love, An Unsolvable Mystery

As night deepened, the moonlight, like water, gently spilled onto Lin Youran's desk, casting a pale silvery glow. Lin Youran sat at the desk, clutching a yellowed photograph in her hand—a picture of her and Shen Yichen from ten years ago, their youthful faces radiating innocent smiles. Now, years had passed, and that smile seemed sealed away by time, untouchable.

Her thoughts drifted back to that afternoon, the sun shining brightly, a gentle breeze blowing. She and Shen Yichen sat side by side on a campus bench, discussing all things related to love. Back then, they were filled with curiosity and longing for love, always believing that as long as two hearts were closely intertwined, they could solve all the mysteries of the world.

"You Ran, do you think love is like solving an equation?" Shen Yichen suddenly asked, his eyes sparkling with curiosity.

Lin Youran paused for a moment, then laughed: "That's a really interesting analogy. So, how do you think we should solve the love equation?"

Shen Yichen thought for a moment and said seriously, "I think the equation for love is the sum of two people's hearts, multiplied by trust, understanding and tolerance, and finally divided by misunderstandings and arguments. The result calculated this way should be happiness."

Lin Youran listened intently, a warm feeling welling up inside her. Back then, they always believed that as long as they managed their love according to this formula, they would reap abundant happiness. However, reality is always much more complicated than imagined.

As time went by, Lin Youran and Shen Yichen's love story was full of twists and turns. They experienced separation, misunderstandings, arguments, and even came to the brink of breaking up. Whenever the night was quiet, Lin Youran would think of that afternoon and the love equation that Shen Yichen proposed, and a bitter feeling would rise in her heart.

She picked up a pen and wrote a line in her diary: "Does the equation for love really exist? Why have we tried so hard for so long, yet still can't find the right answer?"

Just then, her phone rang, interrupting her thoughts. Lin Youran glanced at the screen; it was a call from Shen Yichen. She hesitated for a moment, but ultimately pressed the answer button.

"You Ran, it's me." Shen Yichen's voice came from the other end of the phone, tinged with weariness and apology. "I've thought about it for a long time, and I've decided to call you after all."

Lin Youran remained silent, her heart filled with mixed emotions. She knew this phone call meant their story wasn't over yet, but she didn't know how to continue.

“You Ran, I know there are many problems between us that we haven’t solved, but I don’t want to give up like this.” Shen Yichen continued, “I’ve been thinking that maybe our love equation was wrong from the very beginning. Love may not be a simple equation that can be calculated, but an unsolvable mystery.”

Lin Youran was stunned, a strange feeling of emotion welling up inside her. She finally understood that Shen Yichen had also been thinking about their relationship and trying to find the answer.

“Yichen, you’re right,” Lin Youran said softly. “Love is indeed an unsolvable mystery. We can’t calculate its value with simple equations, nor can we predict its direction. But it is precisely because it is unsolvable that we cherish each other’s existence more and try harder to understand and tolerate each other.”

There was a moment of silence on the other end of the phone, then Shen Yichen's deep and firm voice came through: "You Ran, I want to see you. I want to talk to you face to face. No matter the outcome, I hope we can be honest with each other."

Lin Youran nodded, a surge of courage welling up within her. She knew this decision might complicate their relationship, but she also understood that only by facing the issue head-on could they resolve it, and only honesty could strengthen their love.

The agreed-upon location was a coffee shop they had frequented countless times. When Lin Youran entered the coffee shop, Shen Yichen was already sitting there waiting for her. His eyes were filled with anticipation and nervousness, like a prisoner awaiting trial.

Lin Youran walked over and sat down in front of him. The two smiled at each other, as if they had returned to the carefree days of many years ago. However, they both knew that this conversation would determine their future.

“You Ran, I know we’ve had a lot of misunderstandings and arguments,” Shen Yichen broke the silence. “But I’ve never stopped loving and missing you. I think maybe we both need to give each other a chance to understand and accept one another.”

Lin Youran nodded, tears glistening in her eyes: "I've also been thinking about where the problem lies between us. Now I finally understand that love isn't a simple equation that can be calculated. It requires us to feel it with our hearts, to experience it, and to cherish it."

The two talked for a long time, from memories of the past to hopes for the future, from misunderstandings to mutual understanding. They finally realized that the true meaning of love is not about pursuing a perfect answer, but about accompanying and growing together along the way.

As night fell again, they walked out of the café hand in hand. The moonlight bathed them, as if draping them in a silver veil. Lin Youran looked up at the sky, her heart filled with an unprecedented peace and contentment.

She knew that no matter how the future changed, they would face life's ups and downs hand in hand. Because they had found their own formula for love—unconditional trust, deep understanding, and unwavering acceptance.

As for that unsolved mystery, they no longer seemed to care so much. Because in this world full of unknowns, having each other's love was already the most beautiful answer.
