I feel bad for Haesol, all through her childhood she never had people who treated her like they loved her. So in this chapter Yeonwoo is bringing out feelings she never felt before. She doesn't have anybody to lean on like Yeonwoo did, she has nobody even though she has friends. She was lonely all her life mostly and is uncomfortable to express herself, probably because she has trust issues too.
WHAT THE FUCK! GUYS COMMENT IF YOUR WITH ME IN THIS. WHAT THE FUCKING FUCK IS THIS CRAP.
