8/10 is my rating. This is a 2016/2017 Japanese television drama spanning 2 seasons and 27 episodes (17 in the 1st season and 10 in the second season).
Each episode is about 48 minutes long.
Nao Yoshikawa (Haruka Fukuhara) is a teenage girl who is allowed to rent and stay in her own apartment so she can finish up school in the city. She rents a, too good to be true, apartment only to find out that she has been scammed. Another teenager, Hisashi Uehara (Shunya Shiraisha) has been rented the same apartment and both think the apartment is theirs. They quickly realize what has happened and that neither can afford the apartment on their own so they agree to share. Hisashi is the school heartthrob and has all kinds of conditions – pretty much pretend you don't know me at school. They also have to hide their living arrangements from basically everyone. Over time they develop feelings for each other.

Spoiler ? I liked this but was really disappointed that the male lead's character never really showed an evolution or a reveal that this gruff, arrogant exterior was only a front. It still felt like, even at the end, an unbalanced love. Despite that I did still really like it. It's just it felt like there were so many other better choices in life journey partner she could have made. I know those kind of relationships can work in reality (in a sense) but the one who loves more always winds up, through time, carrying just a tiny bit of heartbreak. So that was a bit disappointing. I wanted to see him madly in love with her and just never really got that.
