Wanted to rate 3/5 but due to recent mangas/huas/was being so low quality i think 4/5 is good mark of this one.
A lot of frutrating moments MMC and FMC are dumpster fires they are (more MMC than FMC) like a compilation of people with problems not to mention i get the feeling they were living in the bubble. I understand why, it's to be entertaining (creating chaos and drama) but also to guide younger generations through problems with more or less practical guide to relationship, some things are effective.
On the other hand there is a lot smoothing over the edges. Some of the actions, decisions and words would need a lot of time to get processed/healed/resolved but author tends to sweep those things under the rug as if those things are comparitively minor. My biggest grind was MMC relationship with his mother, so called stepfather and stepsister. (some things are unforgivable and some are just too awkward but asian fillial piety is idiotic in many cases due to major differences with our 21st century and 20th century and below).
All in all it's not bad, it's fun a little overdramatic (just too much red flags) but you should consume with grain of salt it's foreign for western audience and even aged for Korean society).
