this reminds me of a US show lovelife(?), both basically follow the love life of the main lead and the lessons/events revolving around a normal person's choices.

the 1st guy was kinda the "dream" guy, they met by chance/fate, he was sweet and simple but for young aya he was too grounding and unfit for her luxuries life dreams. (and at the end she regrets it, but on the other hand he really did want the simple lifestyle, which was only her dream after people pressured her, so if they stayed together they'd have probably fought alot and hated each other)
the 2nd guy was exactly what she wanted but HE was too "ambitious" for HER, so he left her
the 3rd guy was the guy she needed to fulfill her luxury living lifestyle until it felt empty
the 4th guy was the result of people's expectations and their definition of a woman's happiness "of a 30+ year old woman to get married and have kids" and it was too much of a burden
the 5th guy was a boost for her ego, a 40 year old divorcee was still "wanted" by someone but he was too young and free spirited so he left her for money
and the 6th guy was her "the one" who actually turned out to be her long time friend! (I'm sorry I'm bad with faces) but he was really a great not unexpected match for her. he was intuitive and since he had a lot of platonic girl friends he was the ideal modern guy for the independent 21st century career woman, he understood their worries and goals ;D

sadly this was too short, and it took me a while to get used to the characters talking to the camera, and (a shallow part of me shall say) the guys were unattractive, but it was a really sweet underrated unexpected gem❤

I never rewatch stuff but I want another drama like this ;(
