Liu Hai: He is innocent and cheerful. The most brain-intensive thing in his life is probably the "Haiwan War" plan. Can he succeed?
Wang Minghai: Liu Hai's best friend seemed to be very fat when he was a child, but now you can't tell it at all. Is he really a male?
Yang Tianhai: versatile, outspoken, with wild intuition, not very good at dealing with Wang Minghai, and has been involved in the "Sea Bend War".
Bamboo horses, bamboo horses, three little ones. The young heart is uncontrollably restless; the young feelings I really want you to know; the beautiful you, please notice it quickly. I like you.
