I'm not entirely sure as it seems to be in a language other than English. But if I were to break it down, 'kekasih' might be a word related to 'lover' in some languages. 'Paksa' could mean 'force' or 'compel' and'rela' might be'relax' or something else. 'Online novel' is clear. It could potentially refer to a situation in an online novel where a lover is forced to do something and be relaxed about it? Just a speculation.
There's no evidence to suggest that 'kekasih paksa rela online novel' is a popular topic in the online novel community. Given that it's a rather unclear and perhaps region - specific phrase, it's not likely to be on the radar of the general online novel - reading public. Most popular topics in the online novel community tend to be more common themes like romance, adventure, fantasy, etc.
You might like 'Ao Haru Ride'. It shares the themes of young love and self-discovery that are present in Fuuka. The art style is also appealing. Also, 'Blue Spring Ride' has similar elements of friendship and romance that could appeal to fans of Fuuka.
In reality, a cartoon dojo might focus more on practical training and safety. In fiction, it could have magical or supernatural elements that don't exist in the real world.
Well, fan comics often focus on specific aspects or characters that fans are passionate about. Cartoons, in contrast, tend to have a broader appeal and might follow a set formula for entertainment. Also, the art quality and production values can vary significantly between the two.
