Look at that face! THAT is the face of a girl totally in love! And this is coming from the perspective of her best friend who has seen this exact look before! Also young Ri-chan is super cute.
@Shewy92 As far as I can tell, it has nothing to do with the exact events in this chapter, but judging by how the first page is 'flashback' shaded, this might've been when Ri-chan just got back from America and her brother is scolding her for not coming back sooner to comfort Nozomi if she was coming back anyway. Then if you notice the last text box, it is also shaded, which seems to indicate it's finishing the text box from the first page. I guess it's just to show a bit more of Ritsuko's relationship with Nozomi and how she feels about this or something
