This is like...really good? I hadn't heard any buzz about it, but it's actually great. Chapters are bite-sized but not actually that shallow. Series is light and fluffy, but has some actual substance to it. It's about adults(!), with an age gap, no less. A good portion of the comedy is just Wanko being an idiot in the way that we usually only are with our loved ones. This is like, my ultimate weakness!
Also Ikeda's art is like, sssooo good now?? Sasameki Koto got the job done but this is like, peak-levels for this style, not even mentioning the dynamism of its framing. The character designs are great, too - Ataru and Sakuma are just so pretty! The distinct lightness with which Sakuma is drawn and its contrast to Wanko's cute and youthful appearance is...really unique.
I wanna make a mean joke about Stretch but I'll just leave it there. Very happy I read this, thanks /u/!
