Ohoooo, out of all six, my favorite is the Dangers in my Heart. Although it is a slow burn romance, I still love the pace. I felt an intense emotions during first season that I had to pause a lot of times to breath. They are just too cute and too sweet for my heart - too much diabetes too, lol. As for Jaku-Chara Tomozaki-kun, I couldn't finish the first season of that. Maybe because another anime series caught my attention that time. Maybe I'll try to rewatch it again.
Ans that Doctor Elise anime, I only try the manhwa version of it but not yet the anime. I didn't finish the manhwa though as I got bored with it. Although in the first few chapters, it is really interesting. I will also check the anime version once I'm done with the others.
As for the rest of the anime mentioned here, well, they are already on my watch list actually. I'm curious which one of those will be added to my favorite, hehe.
I'm glad to know that you also like the last one on this list. It's my favorite because it conveys so many emotions in a simple young love story. I highly recommend that you take back Tomozaki-Kun, Both the first and this second season are spectacular (plus the second season). For the rest, I also recommend the one about the angel and the devil, it's very good.
