悲苦

悲 = 心 + 非 : Beelzebub (b) is looking through his old negatives (非) in front of the Eiffel Tower (ei1). He is reminded of his youth and his lost loves and his heart (心) is filled with sadness and grief (悲). His heart gets so heavy that he drops it on the floor, just for a moment to get some relief.

苦 = 艹 + 古 : Karl Koala decided to repent for his sins and retreated into a cloister inside the space station. There he leads a very simple life full of hardship, e.g. he gave up on eucalyptus and just eats very bitter artificial lawn.
