The Good
⌲ The brilliant episode that is E10 (It's one of the best kdrama episodes I've seen in quite a while)
⌲ Jung So Min's coolness (though she too did not try very hard early on, but improved later)
⌲ Mo Eum
⌲ The final episodes were -mostly- rather entertaining
⌲ The good comedy when not in sad melo mode
⌲ The endless fun bickering
⌲ ML's ex, mostly
⌲ There is no stupid elementary school level dating in this show & everyone has good and relatively immediate relationship goals.

The Average
⌲The acting (Jung Hae In is an excellent actor, but he did not try very hard in this one and some other supporting actors neither)
⌲ There is too much focus on the elders, very much like in a family drama. (then again their plots are not all that bad)
⌲ The chemistry between the leads
⌲ Mo Eum's romantic plot
⌲ Could have said `friends to lovers` done somewhat right, but the flashback content & ML's everlasting love are just so wrong.

The Bad
⌲ The dimwitted and insane mom
⌲ Before E10 the show has been increasingly less and less entertaining as time went on, felt like dropping it at one point.
⌲ The sad melodrama parts felt off to me early on.
⌲ The ex (despite his graceful exit I disliked almost everything about him & his plot )
⌲ The bracelet product placement (though admittedly Cleopatra could have worn that thing)
⌲ The North Pole. (good god)
⌲ Uncle!
