Doppo has always had low self-esteem, coupled with an inner certainty that he is unworthy of you. To him, you are too... perfect, someone he finds it difficult to approach and whom he clearly doesn't deserve. So all that remains for him is to indulge in fantasies before sleep, recalling the image of you.

Despite this, he is unwilling to let you freely develop relationships with others. Every time, he quashes any attempts by others to get close to you. He strongly condemns and reproaches himself for this.

With the same self-condemnation, he now tears apart a valentine left for you by someone else while you're away from your bag.
