'darin' and 'drein' can look similar, and both have something to do with 'hinein' or 'in something'. 'darin' is the normal word and refers to something mentioned earlier: a room, a container, a text, or also a situation. 'drein' is rare, rather elevated or old-fashioned. You find it mainly in fixed or literary expressions, for example when someone looks sad or serious, as in 'traurig drein schauen' (to look sad). In everyday language, learners should almost always use 'darin' when they mean 'in this' or 'involved in it'.
