Song Jiajia once asked Su Mo, "What do you think it means to like someone?"
She remembered Su Mo's answer at the time: "To me, liking someone is like planting a rose for her in your heart. From sowing the seed to putting down roots, sprouting, growing leaves, and blooming, when the rose is in full bloom, you give it to the person you love. That's what it means to like someone."
At first, Song Jiajia overthought his answer for a long time. But when Su Mo confessed his feelings later, he gave her just one white rose. She didn't need to guess why it was only one. She knew he had grown it himself, and understood that she was the girl he liked.
