Mm one is punch drunk love which has what you're asking for. It's not a huge component of the story though if that's what you wanted but you still do get a nice wholesome scene with them
hehe that's why i made this post in the first place and while it wasn't a big part of the story the build up was amazing.
Romance where one (preferably top) has a shitty family and the other introduces them to their healthy family and it's really sweet.
my preference is BL or BG
