I personally enjoyed a lot watching this while I was in high school. Everything is so relatable. Wasting time playing around, career path doubts, unrequited love, sleep-overs, vacations.
Chizuru makes everything so much funnier. He is always spicing things up.
Shun is adorable. He looks like a girl in everthing and his way of speaching is so cute.
The twins are always making fun of someone and Kaname is always complaining but always enjoying their company.
There's lot of angst though the one sided first love of young boys. Mostly of Chizuru. His shy approaches, the moments he zones-out, his uneasiness. It's all well expressed.
Cute cut back scenes to their cute childhood
Note: Don't skip the opening and ending ! They're lovely !
