maybe it's not very well known? (only 4 volumes, no anime) thanks for the recommendation another manga: tsukihime
Chongfei Manual Love so Life (manga) - complete Faster than a Kiss (manga) - complete Que Sera, Sera (webtoon) My Boyfriend is a Jiyiwei (webtoon) Skip Beat (manga) Kore wa Koi no Hanashi (manga) - complete, contrary from Usagi Drop it was done well! Early today someone asked what is a forced plot, Usagi Drop is a great example...
Return of the Condor Hero Usagi Drop Otoyomegatari Faster Than A Kiss Ai Hime: Ai to Himegoto Kingyou Sou Adarshan no Hanayome Hana to Akuma Tale of Genji (by Waki Yamato, no Eng translation as far as I know & only part of the story) Tenchi Muyou & Aats! Megami-sama (technically the ladies of both series are older than MCs') Koi wa Ameagari no You ni Living Game Love so Life
I'm really proud of you guys/gals for not recommending that dreadful shota/yaoi anime. Especially when considering the fact that @Raneday's post didn't exclude Shota-x-Creepy guy from being recommended.
Kiss- this is really good one if you havent read it this is a must Kekkaishi- lol a bit of romance in there and age gap of a year or two 666 satan - again almost no romance B-Shock - good one dont remmember if there is a age gap
It did, where it says "Minimum age should be around Teens/High School age". If there was no age limit I'd have a lot more recommendations.
Soredemo sekai wa utsukshi Dear mine Futari no Renai shoukan Game over +Unbalance x2 +Sensei lock on (it's getting a continuation)
Watashi no shounen (OLxShota) Looking for a father (korean webtoon)(M29yoxF17yo) I feel like i have read a lot of this kind of plot, but i can't recall most of it
To make it grow even more^^ Yankee shota to otaku oneesan: http://m.fanfox.net/manga/yankee_shota_to_otaku_onee_san
Koi Kaze. Man found out he has a young sister. Man ends up sleeping with young sister. One of the greatest love story of the 90s.
