This is the Un-Rizzable Waifu! This waifu is REALLY difficult to rizz. If you try to make any affective or romantic comment, she will inmediately deny you and change the topic. A tip I can give you is to slowly, REALLY slowly, flirt with her undirectly and maybe over time she will start liking you. Tip 2: Do NOT confess to her, if you are doing everything right she will propose to you first. Take your time!
