12-sai.: Chicchana Mune no Tokimeki · review
Keep in mind that this is a romance where the main characters are 12 year olds. Think back to when you were that age, and how you behaved (especially concerning love) back then. If that sounds annoying, embarassing or cringy to you, then this show probably won't be a good choice for you. There's really not much more to say about it than that. There is no depth or tragic backstory to the characters, or some fancy drama build around them. It's plain and simple, 2 couples of kids falling in love, and experiencing what it means to have a boyfriend/girlfriend and being in love ingeneral. Insecurity, blushing, cute and awkward moments, classmates getting in the way, love rivalry, some changes the female body goes through at that time, and so on.
