告白不难过暗恋不失落
[gào bái bù nán guò àn liàn bù shī luò]
This username reflects a sentiment where the person conveys that even if their confession of love (告白) is not reciprocated, they will not be overly sad; similarly, unrequited love (暗恋) does not make them feel lost. It shows an attitude of being optimistic about romantic relationships.
