I just finished up this manga (I got hooked and read it in under 2 days) and am dying for something like this. I didn't like the actions of some of the characters, but I loved everything about this manga. I really got attached to all of the characters and felt bad when bad things happened to them, and it was a very upsetting (I hated the main characters decisions for like the first 80% of the series) but I enjoyed that I was that much into it to actually be upset at a character and despise them in a real-life type of way.

The only other thing that I think is in the same genre as this is Nana. I'm not very familiar with Shoujo/Romance stuff, but if you really really liked Nana and Ichigo 100% and theres something else that you really liked as well that was similar, could you list it?

anyways ichigo 100% is shounen, no matter where you look at it xP

Ichigo?Hmmm, if your talkin about Harems, there is Shuffle, Ai Yori Aoshi, Gacha Gacha, Girls Bravo, Girls Saurus, Pastel, etc.but if not what your lookin for, you can look at my Reading List, most of them are comedy romance...cool? lates

If life throws you lemons...throw them right back...

Just about any harem manga out there?

I've actually been there. Ichigo 100% was one of the first few mangas that I completed and yeah I also looked for something similar. so maybe you wanna try these:

I"s
Hatsukoi limited
Lilim Kiss
Video girl ai
Parallel
Pastel
Love Hina

Don't only look straight, look also to the sides, usually the essential isn't in front of you, but beside you.

i second Video Girl Ai, really great manga
much better than ichigo 100% in my opinion 😀

Mittsu no kokoro ga hitotsu ni nareba...
Hitotsu no seigi wa hyakuman pawaa.

• Getter Robo -

Try suzuka.The story is something similar to Ichigo 100%.

Parallel
Pastel

These two are really good, Pastel has been a long time favorite even though it's been dragged out to death. 😛

this is my set! one! peace!

Hatsukoi limited
Same mangaka, same art style. Closest thing to Ichigo 100% you'll get.

I's

I third Video Girl Ai. It's basically the prototype for Ichigo and it was better IMO. Also Ahoaho basically hit the nail on the head, but if you're looking for series that are of similar format than those fit.

Ah to quickly say, Ichigo 100% is definitely shonen. Guys have romances too man 😛 You can generally tell a male romance from a female one by two extremely general characteristics:

Male
1.Main male character isn't a bishie
2.Main female character/characters have huge boobs and are extremely well proportioned

Female
1.Main male character/characters are bishies
2. Main female character is essentially completely flat

The truth hurts (and is utterly hilarious)

Ichigo 100% was the first manga I read, I loved it and got hooked in the manga world (mainly because I can read much more manga in the times it takes to watch one 30-minute episode of anime... 😐 )

Well anyways, harems are my favorite, he's some of them:
Love Hina
To-Love-Ru
Ai Kora (very good!!)

Manga with secondary romance/harems are:
Addicted to Curry
Mahou Sensei Negima!
MxO
Change 123
Zero no Tsukaima
Shakugan no Shana
All these series are/were pretty good (Zero no Tsukaima's anime is better than the manga)

Hope this helps.

Riches take to themselves wings and fly
Power can depart suddenly from the powerful
Pride goes before a fall
It's an ill wind that blows nobody good
There is no fool like an old fool
Insolence attracts the thunderbolt of the gods

In other words, don't get rich, powerful, proud, old, or insolent, or else you'll lose everything, be struck by lightning, and blown off a cliff (by a proud, diseased wind!).
