Are similar because both focus on complex relationships and emotional growth between the main characters. They explore unexpected love and highlight the personal struggles characters face as they navigate their feelings. Both are really funny to watch.
As far as I've watched and read in the comments, its very similair to the "love is like a poison" since they also live together spontaniously like this and it just overall seem like a funnier version of "perfect propose"
One of the characters is very friendly, and easy to read, while the other character is cold and hard to understand. Those who like these hot and cold couples might enjoy 'Takara-kun to Amagi-kun' as well.
