I recommend Beauty and The Bodyguard, which is also a light novel. The storyline was similar. The male protagonist had changed from the protector of the school belle to a member of a gang of thieves. However, he was not really a bad person. He still had his own justice and principles. Just like " The Girl Next Door Has Grow Up," there were hilarious scenes and sweet emotional lines. I hope you like my recommendation. Muah!
I haven't been able to find any information on the author of the 'just one look novel'. It could be a self - published work, in which case the author may not be widely known. It might also be a new release that hasn't gained much attention yet.
I'm not sure specifically as there could be many novels with that title. It might be about a situation where just one look changes everything. Maybe it's a love story where the main character falls in love at first sight. Or it could be a mystery where one look reveals a crucial clue.
I'm not sure exactly when the next Dragon Ball manga will come out. You might want to keep an eye on official announcements from the publisher or the author's social media.
