Kimi wa Pet, Watashi no Shounen Recommendations
Calm/tranquil vibes. Emotionally confused older female, younger male with trauma. A questionable relationship between people who find themselves attached to the other in a way that's closer than family and not quite romantic (mostly due to feeling they don't have the right or its abnormal), yet ultimately they're complete strangers. Kimi Wa Pet explores more romance while longing for and finding sanctuary in a stranger. Watashi no Shounen explores more the emptiness two people feel and gradually become attached to one another with the anxiety of being unable to define what kind of relationship they have and the fear of it being misunderstood.
