Now, this small arc is just 3 chapters but the way they represented this made me like Maiko more likeable character than how annoying I felt he was before. He's just the perfect friend anyone would want, always being observant of the surrounding. This quiet explains why he got many perverted/important photos. If the story was just this with some more development as a one shot manga it would have got 10/10 from me.
Tl;dr: This arc is way better than the whole manga itself.
