Lin Chuyan and Zhang Jiamu are freshmen. They are pen pals who have known each other since middle school. Both of them have their own secrets and masks. In the eyes of others, they both have a reticent and unapproachable personality, which makes them choose to use the most primitive way of contact in this era of developed Internet - letters, just to make close friends. Without knowing each other's name, voice, or appearance, the two recognized each other as irreplaceable friends. Mutual understanding and support are synonymous with their friendship.
"Since I am a person who can make my own choices, every decision I make is inseparable from your unconditional understanding and support. I have always wanted to say thank you to you."
Intention: In this era of developed Internet, slow down and make friends seriously.
