fluffy romance c-drama with lots of kisses or skinship

I'm particularly looking for a sweet fluffy c-drama that you think is underrated, or underappreciated. It should--

1) have tons of adequate amount of chemistry, kisses, and skinship. 
2) Came out recently, within 2022-2023 

3) have below 30 episodes

4) and it should be fluffy pls, like I'd prefer if it doesn't have too much angst, conflicts or frustrating moments/characters.

I know I'm being too precise but I hope you guys can recommend me some shows that follow some, if not all, of my criterias! TIA

The sweetest one I saw is My Little Happiness... except the year it meets all your requirements. I wonder why you dropped it. Maybe its beginning is not so fluffy, but from episode 10 it gets better and leads start dating in ep. 13 (i think), then it is all fluffy with many sweet and steamy kisses among them.

• Hidden Love (Skinship/kisses If I had to rate it, it would be around 2.5/5 it's more sweet and fluffy rather than "intense". / Chemistry : 4.5/5 / came out in 2023 / 25 eps / No angst at all, there is a little conflict around the 2/3 of the drama with her big brother but it ends within 1 ep so.... all good I guess)
• You Are My Hero (Skinship/kisses 3/5. Same it focuses more on the cute-sweet side / Chemistry : 4/5/ 2021/ 40 episodes :( but I felt like it was too short so ^^/ There is some angst but never between our main characters, the issue is mainly  about their environement and job.)
• Go Go Squid! (Skinship/kisses 4/5, a lot of kisses scenes and the ML lead is very mature./ Chemistry : 3/5 / 2019/ 41 episodes / There is some light drama because they use the "fake dating trope" with some misunderstandings/miscommnications clichés though I swear nothing too heavy to handle and it is one of my favorite C-Drama)
• Put Your Head On My Shoulder (Skinship/kisses 3.5/5 / Chemistry : 3.5/5/ 2019/ 24 episodes / No angst but the 2nd ML is a but frustrating imo. I still liked it)
• Professional Single (Skinship/kisses 3/5 / Chemistry : 3/5 / 2020 / 24 episodes / Very sweet and cute but still 2nd FL is hella frustrating but this doesn't affect the overall vibe and the Main Leads never gave her the attention she was craving for)
• Perfect and Casual (Skinship/kisses 3.5/5 / Chemistry : 3.5/5 / 2020 / 24 episodes / Not much angst or frustrating characters but "Fake Marriage" trope with the miscommunication/misunderstrandinsgs it implies, still very enjoyable)

I still recommend but they fit less :

• To Fly With You (Skinship/kisses 3.5/5 / Chemistry 4/5 / 2021 / 35 episodes / The romance is very sweet and fluffy though there is a big part of the plot that involves their respective parents though they have a real reason to behave the way they are and this doesn't last a long time just around the 2/3 of the drama. And the way things wrapped up for all of them is very beautiful and moving)
• Lighter & Princess (Skinship/kisses 3.5/5 / Chemistry 5/5 / 2022 / 36 episodes / The first half of the drama is perfect for what you are looking for (expect the 2st two episodes which are in the present and then we go back in their college life for around the first half to 2/3rd of the drama) and then we go for some angst and revenge plot (which doesn't involve the FL nor any members of her family. Yet, there is some suffering and frustrating moments in this second part but I do love how things wrapped up for both of them, same for the other characters. This is my favorite C- drama and even though only the first half is fluffy and sweet I do think the whole piece is a masterpiece in the way it balances all the genres.

Hope this can help you find a drama that fits your tastes :) !

Best fit for your request that I can think of: 

• Confess Your Love - fits all your criteria, fluffy and 24 episodes, released last year
• Decreed By Fate - criminally underrated, I love this little drama! Idk if you like historical cdramas but this one is really light and easy to follow. Plus it has a good amount of skinship. Adorable MLs and fun FL, fluffy plot, 16 eps and released 2022. 
• Assistant of Superstar - watching this rn, it's pure fluff and so funny, with tons of kisses. Great if you want some quick mindless entertainment. 24 eps, released 2022

There are several that fit what you're looking for but either didn't come out in the last two years or are slightly longer: 

• Sparkle Love - really fluffy, good bit of skinship also, 24 eps, released 2020
• Meeting You - imo one of the most underrated cdramas if you want adorable fluffiness, there are lots of kisses later on, 28 eps, released 2020
• My Fated Boy - definitely on the cute and fluffy side with a puppy dog ML, 29 eps, released 2021
• Love Is Sweet - first one that came to mind for me when you asked for fluffy cdrama with lots of skinship. Though it is 36 eps and released 2020
