!! Warning: This hanjie is a linea, it is only logical with the constraint that the picture consists of a single curved line, thus each black cell has exactly two of its four nearby cell blacks (except the two ends) !!

Well, a little season to get a foot on the ladder again. For this season, I offer to you a summer theme.
So, ensconce yourself and enjoy the place ;)

Difficulty : ***

Tested, logical (as a linea).
Edge-logic can be useful.
Good blackenage.
