Oh! Finally! Finally Kobayashi acknowledges and expresses her feelings. I thought Kobayashi was pretty straight and I'm not sure if she's attracted to Tooru in a sexual way, but now I think she is more on asexual side. She was never anxious about getting boyfriend or getting married. Seems like she doesn't care that much about this stuff, but she definitely enjoys her comfy almost family-like life with Tooru and feels something that maybe more than friendship, she gets jealous and worries about what Tooru thinks about her. So it could be something like platonic love
