Adorable. Absolutely adorable. Hasegawa being Hiyama's first love is soooo cute. 🥹 Slowly falling for him and noticing all those little things... Ahhh. Looking forward to the rest!
BTW, the mangaka is posting more stuff about them on Twitter. So so so cute. I haven't found a post that indicates that this series is already complete, though I guess it also doesn't have any numbering... 😞
