2..About missing aspect

2.a. They do not show the struggling life of journalist much ..
2.b . The story between celebrity and his past life...
2.c In starting scene celebrity had an argument with his ex that why she was doing so and by the time journalist took the vedio of them and celebrity caught her and their story start and he forget his ex then, so easily ,no melodrama , then whenever she came front of him only 1 time he showed arrogant expressions and then he treat him with a normal expressions.
2.d what is story between celebrity and the one who is always with his ex...
2.e. what thing made them fall for each other..
2.f there is no lovey dove expressions between them ...
What I think ,it could better if this story shows as a drama not in a movie ...

Everything complete in a rush , mr.chanyeol acting is also so loose ,I expect much from him .I watched his acting in Exo's next door ,in that drama he was so cool,arrogant and eventually show his love towards her ,his changing expressions perfectly match with the situation but in this story I didn't found any spark in his acting.
