I found two
- I Reincarnated as the Youngest Prince and All I Want Is a Happy Family! (As this translator suggest)
this one has mc really cute and innocent like franz but his life is so miserable yet he is so positive with everything. I read the novel till the last chapter he is so adorable but i really want to hugs him. glad his brothers finally warm to him and doting him yet he still didn't realize that he already capture his brothers hearts. He only think he is only lowly trash youngest prince that there's no way his brothers want to be close with him. I want him to met franz i think they will be friend and be happy. I like how both this mc lieto and franz still think like a kids even they remember the past life. Though Lieto is still act bit weird not like a 5th y.o because he is too calm and positive but he actually just accepted everything it's like he so optimistic pessimistic. Like he think he is lowly prince so everyone treat him like shit that it can't be help all he will do just thinking about the future and become knowledgeable so someday he can has family who really love him. So now he need to workhard to achieved that and just accepted that everyone didn't like him and neglect him. Like it's so sad
Second is this
The prince of the land of Light
This one has adorable mc too. He has loving brothers and sister and father who love him so much. But he is so op tho and got influenced alot about his past life as an adult. Yet he still like a kid with poor heart. He only want to be happy with his family.
Both manga are on bato and the novel on soyetsu. I prefer the first one because the mc is closer to franz how he act. The only difference is his situation and his goals lol lieto want a family who love him so his goal is to get married with a lady from another country and got the family he dream lol
