Thanks for the update!!
Also, I must say, I love how the author wrote the characters and their circumstances (this is not a spoiler, I am merely theorizing) but if Tassel is the second ML, I think it's wonderful because he's got a legit and sound reason as to why he has to give his feelings for Kasia up unlike in other stories where the 2nd ML gets rejected just for the sake of getting the MC with the 1st ML.
