First of all, the reason why CP is emphasized is because the current idol dramas actually rely on CP powder to get out of the circle. Most idol dramas actually need the audience to crack sugar to get more attention, but in order to make the audience crack CP, there must be a sense of CP between the hero and heroine. Larena didn't have any out-of-circle CP before, but he was very out-of-circle with his white brothers and sisters, but Ren Jialun had many CP's, whether it was Heqi or Allen.
Secondly, Larena is a petite actress, while Allen is not very tall, but it feels good to be with Larena. Judging from the pictures of Reuters sent by fans, Ren Jialun and Larena have a strong sense of CP, and many fans will start to knock on CP in advance after seeing them.
In addition, Larena and Allen are both actors with very good basic skills, and their cooperation will be very harmonious. I just hope "Travel Without Worry" won't be as cruel as "Zhou Sheng as usual". After all, there are too many CP this year, so everyone should be happy.
Finally, at present, Worry-Free Travel is tentatively scheduled to be broadcast in 2023, and it will probably appear in the summer vacation in 2023, because summer vacation is most suitable for idol dramas. In fact, there are several idol dramas this summer vacation, and the results are all good. I also hope that the TV series "Worry-Free Crossing" will become another explosion drama in Larena and Allen.
