This is so, so, so cute. I have the widest grin on my face even after reading the chapter for the sixth or seventh time. As another comment mentions above, this radiates such a soothing warmth and sweetness, it's such a joy to read.
That may be me reading too deeply into it, but I felt a bit of a sulk in Takamine on page 15, and I absolutely love how she just sent her a sticker, it was such a mundane and natural response and felt like such an organic answer to Sakura's hesitation over that earlier in the chapter, and the two conversing through stickers and what seems like messages was incredibly adorable. The chapter's final frame with the last sticker in particular was heartmelting. Sakura's crush is absolutely showing and I am loving every second. "Maybe it's because she goes to another school...?" my foot.
