With the tough competition it faces in its time slot, '7th Grade Civil Servant' ended with lackluster ratings.

According to AGB Nielsen, the drama hit its all-time low on Wednesday with 7.5%. It rose 0.9% to 8.4% on Thursday with its last episode, but it ranked last after 'Wind Blows in Winter' and 'Iris 2'.

The drama had debuted well, and had solid ratings for its beginning episodes. However, the romantic comedy's ratings declined with the beginning of the other dramas. It did manage to bounce back into second place ahead of 'Iris 2' for a few weeks, but fell back again into last spot later on.

Meanwhile, 'Wind Blows in Winter' ranked #1 once again this week with 15.1%, and 'Iris 2' followed with 10.3%.

'7th Grade Civil Servant' will be followed by Shin Se Kyung and Song Seung Hun's 'When A Man Loves'.
