Do you know anything about japanese guys?

I met a japanese guy online and he is 6 years younger than me he's in his early 20's, suddenly few weeks ago he started to text me like literally everyday in the morning and in evening good morning and goodnight and he would ask me always how i have been that keeps happening literally everyday although i don't ever text him or talk a lot with him i almost ignored his messages but he kept on texting me and now suddenly started to ask me "am i a good boy" 😅😅 "am i handsome boy" and its soooo strange to me now, i wanna know is this normal for japanese guys or is he trying to flirt with me 😅
