This one will always have a special place in my heart because it's the first BL I ever watched (surprised I watched more after lol). I highly recommend it, this series is so well done, and while there are a few gaps in the characterization, it's so soft and sweet you can forgive it.

The intimate scenes omg...blush, but worth it.

The side couple I did like, it's a nice contrast to the main couple.

My advice however is not to read the comments as you watch (spoilers abound) but so good. I will rewatch when I get up the courage too, and while I won't spoil anything for you, prepare your heart for this one.
