I don't know how in people's eyes, but, there is a process in their relationship. Not directly, they have the same rhythm from time to time but I see reactions that gradually appear.
Honestly, I really like this, from all the manga that are themed about club activities, I prefer this one. Stick to the original goal, theme and do a little random activity. I see too many clubs in manga that have no characteristics, like D-Frag and many more.
This manga has everything, cute art and also comedy that is unexpectedly interesting.
