I very much liked the way story was delivered much like The Lake House in which the two main leads were able to communicate with each other through letters 

the only differences those two tales have are the time difference and the way of communicating with each other..and I like the idea of them communicating through smartphones 

I highly recommend this manhwa to those who love time lap, time travelling or dimensional bridge romance. 

I gave 9.5/10 to the story because it was a bit rushed.
