"Didi..." She picked up her phone and saw a message from him.
"I want to see you, can you come out?" He is not good at expressing, and his love for her can only be expressed through actions: a "good night" every night, a blessing on holidays, a gift on her birthday...
Perhaps, their love is so dull, time passes by like this, and they become inseparable from each other, making up for each other's regrets.
Good night Sam, I will always love you!
