This manga is a great example of how to have complications come up in romcoms without introducing a love triangle or a misunderstanding where one person thinks the other is cheating.
Relationships can have complications that don't involve other romantic interests getting involved.
It's really refreshing to see characters just talking to each other platonically without any romantic tension, while the series itself still has some tense feelings in it due to the complicated family dynamics or friends dynamics.
This has been great so far. Really glad I read it.
