I don't know if this question was already answered or if it is answered somewhere but if it isn't much of a spoiler.... Who's the unrequited love? (Like which LI but i don't know how to type it so it sounds normal-)
[Tbh i would say it's Linnet since she likes the MC's brother... But it can also be someone else tho i feel like it's most likely her if she is a Li |Yes I'm dumb|]
