@Sova Thanks to your group for the translations! If I may give one small piece of advice, this is the fourth or so strange/obscure translation for names so far in this series - it should almost certainly be Takahashi as a surname if it was written as 高橋. Is the raw providing furigana for names? If not, a helpful resource is Jisho.org’s name database. If you search up ‘高橋 #names’ it’ll give you the most common pronunciation for name kanji. 😇
Natsumi is pretty damn cool. Not for nothing Yuuto fell for her. I imagine would be a gap similar to our main couple. But I've thought he already had her as a big sis and was interested on his friend with a similar hobby.
