Why do I feel familiar with the art??

I was founded the author acc in X and this's actually their debut manga, so I think their art style just kinda similiar with Niyama(Ask and You Will Receive) and Mikka Mita(Shima-chan Chi no Tsugai Jijou) but instead copying I think it's more the author combined the art style so it's look cute like niyama but also look so sharp like MikaaMita(absolutely the top)
