Didn't seaweed sleep with Beckham for a long time? What did you say to Song Siming for the first time?

Song Siming made a mistake. . . That night, seaweed's menstruation came and got it on the mat. Song mistakenly thought that seaweed was the first time. . .

Later, Song mentioned in front of seaweed that seaweed still had OS in its heart. How could it be the first time? (Something like this)

The arrangement of this plot may also be that Song thought seaweed was the first time, so he was very kind to seaweed later and felt that he could not be sorry for the girl who gave it to him for the first time. .
