Its so cool the fact that they had a travel back in time at a moment whr the heroine was anticipating for the future and all she can think of is the good things in the future before she got suddenly brought back to the past. Its rare since most stories travel back to the past after a traumatic event or even death(๑•ㅂ•)و✧
I think this is pretty realistic. Even if u reincarnate, doesnt mean u could do anything and everything. This shows how even if you were once an adult, this kind of things is still difficult to handle.
