I am crazy for the teacher student plot and that is the reason i watched this drama.
The most disappointing thing was, like there is always one point in all the dramas where even the jerks finally open up to the female lead, but here it never happened and it just ended like that.
The ending is unclear and looked very incomplete. Even if there was a message behind it, they failed to deliver it.
Overall, I would love a YouTube compilation of such a drama (as some of the scenes were lovely) but to waste hours watching it would not be worthwhile.
