Any romantic/comedy/shoujo/slice of life manga that you can recommend?

Hmmm...the only series that I can think of at the moment with those genres are Skip Beat and Kimi ni Todoke. I don't know if you've read these yet but I only recall them because they have an anime counterpart too. Skip Beat is the story of a girl who goes into the acting field to get revenge on a girl who used and ditched her after he became a famous singer. Kyoko, the girl, eventually learns to love acting and the story is about her progress as an actress. The main guy, Ren, is a famous actor who initially didn't like Kyoko because he thought that she wasn't taking acting seriously. He eventually changes his opinion about her and starts to like her. But then Sho, the guy who used Kyoko, comes back into the picture and then the drama ensues. I like this series mainly because of Kyoko. She's a strong female protagonist. I also like her reactions to certain things. It's just too funny. Kimi ni Todoke's main female character started off as this outcast or loner. Her classmates were scared of her because she reminded them of the girl from "The Ring" movie. The truth is that she's a really shy girl who's too timid to make any friends. Things start changing when the popular guy, Kazahaya, starts talking to her. This one is a cute series.

I strongly recommend Midori no Hibi. It's a perfect manga for the genre of romantic, comedy, shounen, and bit of action. It also has an anime adaptation with only 13 episodes. In case you haven't watched or read it yet, the story is about a guy who didn't even have a girlfriend for 17 years and being of rejected of every girl that he attempts to go out with because of his being infamous delinquent. But there is this one girl who's secretly in love with him but doesn't have the courage to approach or talk to him about her feeling. All she can do was just to stare at him at the train station. Until the day came the this girl became the guys right hand literally. Then that's how their story begins. The anime of Midori no Hibi was just recommended to me by my office mate so I decided to watch it. As I finish watching the anime, I got addicted to it and its soundtracks just keep on playing to my head for weeks. I did a research about this anime and found a trivia about a huge story difference between its anime and its manga. It is then that I decided to read its manga and I never got frustrated. I'm glad that I've watched the anime first before reading its manga. I also recommend it to my friends and even to my girlfriend who is not an anime fan but they became one just after watching it. They even ask for more but the anime did really end at episode 13. That was the time that I gave them the manga version. All of my friends that I recommend this, no one gave a negative feedback. Instead, they all fell in love with it too. -)

If you haven't read it yet, Lovely Complex is a pretty funny romantic comedy manga. I actually enjoyed the anime more though. Mermaid Melody is cute too

Itazura Na Kiss is one of my favorite romantic anime. Playful Kiss is a korean adaptation of this anime. Also It started with a kiss is a Taiwanese adaptation of this anime. You can also try watching Nodame Cantabile which is a very good romantic anime.

i would recommend kaichou wa maid-sama and special a if it's shoujou you're looking for. they also have comedy, romantic factors.

i would recommend katekyo hitman reborn. a bit of comedy, action and drama, the manga is on going and the anime is ongoing as well.

try to read fruits basket or full metal alchemist brother hood... fruits basket is a story of the cursed sohma family who turned in zodiac animals once they was embraced by opposite gender.. FMA: brotherhood is a story about two alchemist brothers searching for philosopher stone so that they can back their lost body but as the story goes, they found out that it was they're father who is the living philosopher stone...

Read naruto. It's funny and romantic.
