But if you've read the novel. Kallisto is literally perfect for Penelope. He protects Penelope with his whole being, gosh he would even go berserk if someone just literally touch her. He is also willing to sacrifice his life for her. Like dude, there's even a part where he is so willing to take his own life if Penelope stopped breathing. Like he was so firm on the idea to die right after her. Then don't get me started on how he respectfully abide her wishes on fulfilling her dreams on becoming an archaeologist. The dude literally waited for 5 years for her even tho he get anxiety whenever she's not around. This ain't even half of what Kallisto has done for her.
Gosh, sorry for the long comment. I just loved Kallisto you know when I read the novel

i feel bad for Eclise since hes only a 2nd male lead i was even rooting for him
