Both are heartwarming stories about a group of friends who go through days of high school together. They both take place around similar times (When we were young 1996 and I don't want to be friends with you - early 2000s) and have very similar vibes.
This drama is also a remake of the same Japanese drama so the plotline should be pretty similar. The premise of both is about a teacher who takes one of her students away from an abusive household.
There are many similar plot points, but in general so I don't spoil anything, both are great romances with an intriguing overarching plot. The male leads are both princes while the female leads are from a different "clan". Ten Miles of Peach Blossom has more fantasy elements, but the development between the leads are similar (they get together early on) . If you love one, you'll definitely love the other!
Same lead actor, director, and writer. Both have really similar vibes.
Aaron plays pretty much the same role (CEO of a company) and the female lead also works for the company.
I recommend pretty much all adaptations of Itazura na kiss. The personalities of the leads and some elements of the plot are very similar.
They are both based on Itazura na Kiss, though Love in Tokyo is a much better remake.
