Light novels with childhood friend romance

[BWTraveller]

Pretty simple request here. I haven't really seen all that many romantic LNs (excluding harems, which while I like them can be very different from a standard one-to-one romance), and the ones I know tend to be about strangers falling in love. I was just wondering if there were any LNs with sweet romantic plots (don't necessarily have to be "the" plot: Shana for instance was a great romance despite being built around a multiversal battle) in which the core pair are childhood friends.
