Shi Nian hid the leukemia diagnosis certificate, used the lie of "going abroad to study" to embark on the road of treatment alone, and wrote several years of pain and longing into unsent letters.
Lu Xingyu thought her alienation was due to lack of love, but after her sudden death, he understood the torment of her cross-country treatment from the letter.
For a long time after that, Lu Xingyu guarded a box of letters and never married.
Intention: Use lies to hide deep feelings, use long-term care to release regrets
