I'm losing my interest in this with each new chapter. The original couple was cute and fun and I really liked them but as time passed mangaka forced 2 more different couples into this, now OG ones gets literally 1/5 screentime or something because of it and almost zero new cute stuff from them.
The co-worker duo is still acceptable but shota - adult one is completely one of the most boring thing I've ever seen, and for some god know reason mangaka is drawing them way more than others.
