The speaker feels lonely in adult life and says so right away: adulthood "doesn't suit" them, and adapting is hard. They admit they've drifted toward Google instead of people because it's easier, which says a lot about how isolated they've become. They do have a few people around, but it isn't enough. What they want is one person who belongs to them alone.
The middle of the poem turns into a long wish list: someone to listen, hug, laugh, watch movies, dance, cry, and stay "till my end." The simple, repeated "To..." lines make it sound like a heartfelt confession spilling out. The speaker even questions themselves, asking if they're possessive, then answering "I'm desperate." That honesty is the poem's most striking moment. The mood is vulnerable, tender and a little sad. The last line, "Where are you? I miss you already," ends on hope, as the speaker misses someone they haven't met yet.
