Here are some of my favorite romances, some have good development and others are romcom's done right.
If you are looking for "pure romance" with kissing scenes, these anime will get what you want. I recommend to start from Golden Time to White Album just in that order, you won't be disapointed ^^
The anime's I watched more than once because there are just so amazing.
This list will tell you which anime did i watched.:D
