no, I agree with you, it should/could be Kase. Love is not perfect, falling in love can be messy and chaotic, things/circumstances can get in the way.
Plus, I understand feeling unworthy of someone who is just so totally - albeit innocently - in love with you (aka like a "puppy"), thus kinda running away from them.... We shall see how it turns out ^^
^^ hahah thanks ;) and same!
It is always refreshing to find a story that kinda differs from your usual guys-just-end-up-together-from the start-storyline in yaois, cuz that is more realistic in my opinion... cuz let's be honest, it's kinda rare that you find the "right" guy for you from the get-go.
now, let's see if the straight guy - who actually has a GIRLFRIEND (if I remember correctly) - gets back into the "side-chick" position ;) heheh

I guess I'm alone rooting for Kase. Although it's more understandable for people to root for the second guy now cause for the first chapter we already have more background of the second male lead with the mc compared to Kase. Kase was just portrayed as someone who "left" - but since I'm trusting there's more to this, I'll side on Kase cause tbh, the way he smiled purely and passionately went for his dreams moved me (even with just few panels and pages it felt beautiful).
I don't mind if the second lead gets the mc though cause their story together is also interesting and cute ~ seeing Kase just pursue his passion is inspiring and moving and I think it's one thing that draws and will draw me more into this manga... Somehow I think what I'm currently feeling towards Kase as a character is also similar to how the mc felt for him in the past (idk now).
