@KoreJi I also read the novel ahead...... man, the banter is just so good. I gained a lot of contemplation material, even questioning myself "what is an adult? What is common sense?". I have a feeling there should be a drama show somewhere with this exact same premise...... or not?
To you guys out there, yes, this manga got 8.5 stars for a reason.
It should have a "Seinen" Tag
