Definitely, this ending clearly shows us that by meeting the expectations of others, leaving our own identity aside, in the end it will only cause us suffering, guilt, remorse.
and this becomes an endless cycle whatever the universe may be.
In the end DEW realized his mistake but he had already hurt everyone including himself for not daring to express his desires, in the same way MUM if he had dared to speak none of this would have happened.
DEW MUM confrontation was spectacular, they introduced us to the plot that I lived with them at that time. How great are these actors to be so young, they have a promising future.
