Both are cute Japanese BLs. If you like Kieta Hatsukoi's hilarious plot you'll definitely like Ossan's Love as well. Both can he funny when needed but can also be emotional and feel authentic. Both have at times the 'over the top' type of acting that has you laughing to the floor and is so common with jdrama. It has real struggles and makes you immersed into the story. Definitely worth watching.

The struggles youth goes through, but Go Ahead deals with a more complex family structure, Record of Youth is a bit more light-hearted.

It might be because I just finished both of them around the same time but I often thought their similarities how both are struggle of youth and it is heart warming.
