The movie version has a different end. The series are based on the movie, only that in the series they meet 8 years later.

Both stories focus on the development of friendship in school into their adulthood. Throughout the drama, a development in characters can be seen. Friendships gained and lost as they grow up. Some light humor.

Both dramas are school based dramas Love O2O is university based while Rush to the Dead Summer is high school based. The leading actress in both dramas is the same. The storylines give off a refreshing and youthful feel.

Both are time travel and princess related only with the twist of sex change but it is a very funny and odd TDrama

One is Korean Drama the other is Japanese Drama + Movie.
In one the main lead is a girl in the other it's boy.
Both have a time traveling theme. In both it took some time to the main lead to understand the situation… The girl is an actress, she think it's about the period drama she was filming since it's the same period with people with the same name... The boy was in a sort of historic theme park and meet an important historic personage who had a spectacle in the park… So they are both involved with some historical facts particularly for Nobunaga Concerto. They both have some futuristic tools they brought with them in the past. They are plenty of funny moment.
There is more romance in My Only Love Song, and it's ending is happier than Nobunaga Concerto.
