I have actually re-read it, i was wondering why did I put 5/5 in my personal data base well i came to a conclusion that I was a bit hungry at the time for some normal relationship in manga (where you go all bases and timeskips and etc. a change from mediocre romcoms where kissing is the height of build up and sometimes at the end you see a time skip). That said 4/5 new rating subjectively Story 6/10 While at first read through it was unique for me the story after i re-read it was bland nothing to shocking besides the H-scenes which actually take upa lot of chapters considering the manga is short. Though you see some changes some hurdles and struggles of relationship and conflicts within, how some people are afraid of change and learn to embrace it and how some people learn to become self guided rather than guided by others.
This story is more about teenagers embracing young adult world of love and sex and sadly that's the main story other life problems are in the background quite distant even. Though what i like is a realistic take, no cliche, real people here though overly sexualized (what is shown at least).

Art 8/10

Characters are drawn with more or less real proportions and facial features, background is detailed and realistic. Panels are easy to navigate, speech bubbles are easily recognizable.

Characters 7/10

All in all we have Female Lead(FL) and Male Lead(ML) few supports 2 girlfriends from FL and one love rival and from ML side 1 sister and 1 love rival.
FL friends are different and one is energy buildozer (extroverted) other one is deep sea (introverted) each one of them helps FL to understand oneself and helps they help to push her own cognitive limit and realize "womanhood"....Love rival is well the same as friends and like small bump on the road to success not so memorable but helps the story push forward. ML side well he is more like a child (love-sex wise) and every possible characters serves as guide for him on this matter but ML was far less interesting love rival was well a conflicted girl (she is a villain turned grey->between bad and good). All in all it's fresh to see that besides FL and ML supports have their own life that goes separate way forward.

Enjoyment 8/10

I enjoy seeing life happening in art(movies, books, games and etc.) when you believe what is happening there might actually happen in our world i could finally turn of my brain and simply enjoy a swim though H-scenes might disturb that swim. So if not for too much H-scenes it would 9/10 or 10/10. This genre deserves to be called SLICE OF LIFE you peaked at important moments of other people you learned and you broadened the horizon of you mind.

Overall 7/10

It was good, mild and sweet though overly sexualized to my liking. I would be more interested in more slices of life of them becoming adults rather than seeing sex happening (i blank screen would be enough to confirm that their body and mind were connected). This may sound boring but boring is better than drama train without reason as if heaven and hell playing their tunes with two individuals.
Though one thing got me wondering is true that women after having unprotected sex understand their partners better? (Gotta research that, sounds kinda scary if true men would need be more chaste too then)

-Spoiler-though a small one i think

ML is kinda a cheat though there wasn't penetration with love rival they still had quite a few dangerous moments and lastly pussy rub until culmination which is classified as sex in my humble opinion so kudos for girl shame on a guy temptation may be great but a guy can almost always shake the opposite gender off even when aroused (it's hard but hey we are not animals that live by pure instincts).
